Write the first three terms of the G.P. whose first term and the common ratio are given below. (ii) a = √2, r = √2

Write the first three terms of the G.P. whose first term and the common ratio are given below.
(ii) a  = 2, r  = √2
Solution :
First term (a)  = 2
Second term  = ar = 2(2)  = 2
Third term  = ar2  = 2(2)2  = 2(2)  = 22
Hence the first three terms are 2, 2, 22
