If the third term of G.P.is `4`, then find the product of first five terms

Explanation

To solve the problem step by step, we will use the properties of a geometric progression (G.P.).

**Step 1: Understand the terms of G.P.**
In a G.P., the terms can be expressed as:
- First term: \( a \)
- Second term: \( ar \)
- Third term: \( ar^2 \)
- Fourth term: \( ar^3 \)
