Web1/16 = 4(1/2)n-1 1/64 = (1/2)n-1 1/64 = (1/2)n · (1/2)-1 1/128 = (1/2)n n = 7. Thus, there are a total of 7 terms in the given geometric sequence. Note: The form for the general term of a geometric sequence can be very useful. To find the sum of the first n terms of a geometric sequence with first term a1, and common ratio r, one may use the following formula: WebAn = A1(r^(n-1)). The idea is that because they gave you: a3 = 32 and a5 = 512 you can now find A1(first term) and r (the common ratio). Now, you can find any term after that.. An = …
