How do you use first then next finally?
We use a comma after “first”, “next”, “then” and “finally” when they introduce the sentence that describes the action. “first”: for an action that happens before any others. We can also use “first” at the end of the sentence. “I have a lot of work to do.
What type of words are first next then?

What is the sequence in math?
In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.
What is the number in the * Cell 88 63 25?
Answer : The missing number of the given series is 17.
What is the formula for sequence?
A geometric sequence is one in which a term of a sequence is obtained by multiplying the previous term by a constant. It can be described by the formula an=r⋅an−1 a n = r ⋅ a n − 1 .
What is the sum of all odd numbers from 1 to 50?
Answer and Explanation: The sum of all the odd integers from 1 to 50 is 625.
What is an infinite sequence?
An infinite sequence is a list or string of discrete objects, usually numbers, that can be paired off one-to-one with the set of positive integer s {1, 2, 3.}. When the sum of an infinite series is finite and definable, then that series and its corresponding seqeuence converge.
What is a sum to infinity?
An infinite series has an infinite number of terms. The sum of the first n terms, Sn , is called a partial sum. If Sn tends to a limit as n tends to infinity, the limit is called the sum to infinity of the series. a = 1st Term. r = 2nd Term ÷ 1st Term.
What symbol does infinite sequence have?
The infinity symbol, ∞ , is often used as the superscript to represent the sequence that includes all integer k -values starting with a certain one. The sequence of all positive squares is then denoted as: (ak)∞k=1,ak=k2. A Convergent Sequence: The plot of a convergent sequence (an ) is shown in blue.
How do you tell if a sequence is finite or infinite?
A sequence is finite if it has a limited number of terms and infinite if it does not. The first of the sequence is 4 and the last term is 64 . Since the sequence has a last term, it is a finite sequence. Infinite sequence: {4,8,24,…}
What is finite number?
more A number that is not infinite. In other words it could be measured, or given a value. There are a finite number of people at this beach.
Is zero a finite number?
1 Answer. There is no rule, and it depends on the context. If you’re worried about things being very big, then zero is an OK value to have, and you’d count it as a finite quantity.
Can you expect the pattern to continue infinitely?
Answer: If we are talking about patterns of numbers, it is usually infinite. The pattern only continues at the given condition.
What is a finite?
1a : having definite or definable limits a finite number of possibilities. b : having a limited nature or existence finite beings. 2 : completely determinable in theory or in fact by counting, measurement, or thought the finite velocity of light.
What is finite and infinite geometric sequence?
An infinite geometric series is the sum of an infinite geometric sequence . This series would have no last term. The general form of the infinite geometric series is a1+a1r+a1r2+a1r3+… , where a1 is the first term and r is the common ratio. We can find the sum of all finite geometric series.
What does R equal in a geometric sequence?
This sequence has a factor of 2 between each number. Each term (except the first term) is found by multiplying the previous term by 2. a is the first term, and. r is the factor between the terms (called the “common ratio”)
How do you find infinite sums?
For example, follow the steps to find this value:
- Find the value of a1 by plugging in 1 for n.
- Calculate a2 by plugging in 2 for n.
- Determine r. To find r, you divide a2 by a1:
- Plug a1 and r into the formula to find the infinite sum. Plug in and simplify to find the following:
What is finite geometric sequence?
1.5 Finite geometric series (EMCDZ) When we sum a known number of terms in a geometric sequence, we get a finite geometric series.
What is the difference between finite and infinite geometric sequence?
A finite sequence has a starting number, a difference or factor, and a fixed total number of terms. Infinite sequences don’t have a fixed number of terms, and their terms can grow to infinity, decrease to zero or approach a fixed value. The corresponding series can also have an infinite, zero or fixed result.
What is the example of finite geometric sequence?
For example, the sequence 1,2,4,8,16,32,… is clearly geometric, as each term is the previous one multiplied by the common ratio, which, in this case, is 2.
What is the sum of first 25 terms of the geometric sequence 5 5 5 5?
The sum of the first 25 terms of the geometric sequence is 5.
What is the sum of the first 5 terms?
The sum of the first 5 terms would be: n + (n+d) + (n+2d) + (n+3d) + (n+4d), which is equal to 5n + 10. The sum of the first 10 terms would be: n + (n+d) + (n+2d) + (n+3d) + (n+4d) + (n+5d) + (n+6d) + (n+7d) + (n+8d) + (n+9d), which is equal to 10n + 45.
