Let's say we have the simplest of arithmetic sequences. {1,2,3,⋅⋅⋅,n}{1,2,3,⋅⋅⋅,n} And what I want to think about is what is the sum of this sequence going to be? And the sum of a sequence, we already know we call a series as following: Sn=1+2+3+⋅...
The formula for the sum of the first nn terms of an arithmetic sequence is Sn=n(a1+an)2Sn=n(a1+an)2 How To: Given terms of an arithmetic series, find the sum of the first nn terms. Identify a1a1 and anan. Determine nn. Substitute values for a1, ana1, an, and nn into the ...
We define an arithmetic sequence as a sequence which has a common difference between all consecutive terms. This sequence is very useful in simulating certain scenarios in which there is a common difference.Answer and Explanation: The general formula for the arithmetic sequence is An=A1+(n−1)...
