`a_1 = 2, r = pi` Write the first five terms of the geometric sequence.

Thursday, October 1, 2015

The first five terms of geometric sequence can be computed with formula, such that:

`a_n = a_(n-1)*q`

`a_2 = a_1*q => a_2 = 2*pi`

`a_3 = a_2*q => a_3 =2pi*pi = 2pi^2`

`a_4 = a_3*q => a_4 =2pi^2*pi = 2pi^3`

`a_5 = a_4*q => a_5 =2pi^3*pi = 2pi^4`

Hence, evaluating the five terms of geometric sequence yields `a_1 =2, a_2 = 2pi, a_3 =2pi^2, a_4 =2pi^3, a_5 =2pi^4.`
