Question

the 2 nd term of a gp is b and the common ratio is r if the product of the 1 st three term is 64 find the value of b​

Answer 1

Answer:

Let a be the first term and r be the common ratio respectively. Then

Second term of G.P. is

ar=4. (from the question) …1

4^(th) term of G.P. is

ar^3=64 (from question) …2

Divide 2 by 1

ar^3/ar =64/4

r^2 =16

r=4
