Question

# If l, m, n are the terms of a G.P which are +ve, then

- 3
- 2
- 1
- 0

Hint:

### The formula for the n^{th} term of the geometric progression is:

**an = ar**^{n-1}

where, a is the first term

- r is the common ratio
- n is the number of the term which we want to find.

^{n-1}

## The correct answer is: 0

### Given : l, m, n are the terms of a G.P

We know that in GP

where,

- a is the first term
- r is the common ratio
- n is the number of the term which we want to find.

Using this :

Substituting these values in :

We know that

Using these formulas and further simplifying

Thus, 0
