Question

If $a squared comma b squared comma c squared$ are in A.P then $c o t invisible function application A comma c o t invisible function application B comma c o t invisible function application C$ are in

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

The correct answer is: A.P

In the question it is given that $a squared comma b squared comma c squared$ are in A.P and we have to find the relation between $cot open parentheses A close parentheses comma cot open parentheses B close parentheses comma cot open parentheses C close parentheses$ .
Step1: Using the relation of A.P
If $a squared comma b squared comma c squared$ then $b squared equals fraction numerator a squared plus c squared over denominator 2 end fraction$
