Question

Find the indicated term of the given geometric sequence.

a1 = 11, r = 3.4, n = 7

Answer 1

a₇ = 16992.84

Explanation:

Given that,

a₁ = 11, r = 3.4 and n = 7

The geometric sequence is given by :

`a_n=a_1\cdot r^(n-1)`

Put all the values,

`a_7=11* (3.4)^(7-1)\\\\=11* (3.4)^6\\\\=16992.84`

So, the seventh term is equal to 16992.84.
