`a_1 = 8, r = 2` Write the first five terms of the geometric sequence.

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 = 8*2 => a_2 = 16`


a`_3 = a_2*q => a_3 =16*2 = 32`


`a_4 = a_3*q =>a_4 =32*2 = 64`


`a_5 = a_4*q =>a_5 =64*2 = 128`


Hence, evaluating the five terms of geometric sequence yields `a_1 = 8, a_2 = 16, a_3 =32, a_4 =64, a_5 =128.`
