Determine the sum of a series

WebA geometric sequence is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed number. It is represented by the formula a_n = a_1 * r^ (n-1), where a_1 is the first term of the sequence, a_n is the nth term of the sequence, and r is the common ratio. The common ratio is obtained by dividing the current ... WebSumming a Geometric Series. To sum these: a + ar + ar 2 + ... + ar (n-1) (Each term is ar k, where k starts at 0 and goes up to n-1) We can use this handy formula: a is the first term r is the "common ratio" between terms n …

WebThis is the formula to find the sum of the first n n terms of the sequence. To evaluate it, the values of the first and n n th terms must be found. Sn = n 2 ⋅(a1 +an) S n = n 2 ⋅ ( a 1 + a n) This is an arithmetic sequence since there is a common difference between each term. WebThe sum from n=0 to infinity of a series is not always the same as the sum from n=5 to infinity of that series, because the first few terms are not counted towards the sum. You can compensate for this by using the proof in previous videos to discover that given that n starts at a constant b, Sn-rSn=ar^b, so Sn = (ar^b)/(1-r). This edited ...
