Question

Given the first term and the common ratio of a geometric sequence find the seventh term of the sequence. a1=2 and r=6​

Answer 1

93312

Explanation:

We can use the geometric sequence formula

a= a1(r)^n-1

Substitute:

a=2(6)n^1

a=2 *6^n* 1/6

a=6^n*1/3

Substitute "7" for n:

a(7)=6^(7)*1/3

a(7)=93,312
