Answer:
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
