Question

# If a,b,c are in A.P then are in

- A.P
- G.P
- H.P
- A.G.P

Hint:

### As we know that when a, b, c is in AP. Then 2b= a+ c. Also, to find the relation between first we will have to find the value of the three in terms of a, b and c then after looking at the values we can determine the relation.

## The correct answer is: A.P

### Given a, b, c is in AP.

So, b-a=c-b or, 2b=a+ c

also, a=b-d, c=b +d, d is the common difference

Now, we know that a+ b+ c=2ss=

Now, cot cot cot
