Sn= (n/2)×(a + l), which means we can find thesum of an arithmetic seriesbymultiplying the number of terms by the average of the first and last terms. In the equation: nis the number of terms; ais the first term; and lis the last term. ...
sequence that increases by 1) that sums to 345.This calls for the sum of an arithmetic sequence given that the first term is k, the last term is g and with n elements, which is: (n*(k+g))/2.So, since it is a sequence of n consecutive numbers starting at k and ending at k...
Based on the answers you found to each equation, find the one that was incorrect. 5.The answer is6How did we get here? Read the problem: Fill in the blank: __ + 12 = 18 Using a number line, locate the 12 and place your pencil on the line. ...
, the equation becomes , so the sum of the first n terms of the arithmetic series, S, is equal to one-half the number of terms multiplied by the sum of the first and last terms. That is, . Find the sum of the terms in the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. ...

【题目】 A series is the sum of the terms in a sequen ce, so an arithmetic series is the sum of the terms in an arithmetic sequence. Let s represe nt the sum:$$ m : S = a _ { 1 } + a _ { 2 } + a _ { 3 } + \ldots + a _ { n - 2 } + a _ { n - 1 }...
Geometric Progression, GP Geometric progression (also known as geometric sequence) is a sequence of numbers where the ratio of any two adjacent terms is constant. The constant ratio is called the common ratio, r of geometric progression. Each term theref
