Which of the following is the missing term of the geometric sequence in which a1= 2 and a3 = 200?

20

Step-by-step explanation:

Given that the first term of a geometric sequence is 2 and third term is 200.

We have to find the middle term

A geometric sequence will have terms of the form

Since first term is 2, ...i

Since third term is 200, ...ii

Divide equation ii by i to get

Because increasing sequence, r cannot be negative so only positive value is take.

II term =

Hence missing term is 20
