Answer 2

Explanation:

Let the common ratio be r and the terms be a,ar,ar2,ar3,ar4

and so on in G.P.

Also, given that the third term is 19

⇒ar2

=100 ...(1)

Therefore, the product of the first five term is given by,

a⋅ar⋅ar2.ar3.ar4.=ar5

a⋅ar⋅ar2.ar3.ar4.=ar5

From equation (1), substitute ar

2

=100; we get

a⋅ar⋅ar2.ar3.ar4.=ar5

Thus, the product of the first five term is

10*5
