The third term of G.P. is 4. The product of its first 5 terms isA. 43B. 44C. 45D. None of these

Given: Third term of G.P, T3 = 4

To find: Product of first five terms

We know that,

Tn = arn – 1

It is given that, T3 = 4

ar3 – 1 = 4

ar2 = 4 …(i)

Product of first 5 terms = a × ar × ar2 × ar3 × ar4

= a5r1+2+3+4

= a5r10

= (ar2)5

= (4)5 [from (i)]

Hence, the correct option is (c)
