Question

If a, b, c are in A.P., then the following are also in A.P.
$\frac{1}{bc},\frac{1}{ca},\frac{1}{ab}$.

• A. True
• B. False

Answer 1

The correct option is A True

We have,

$a,b,c$ are in $A.P$

On dividing by $abc$, we get

$\frac{a}{abc},\frac{b}{abc},\frac{c}{abc}$ are also in $A.P$

$\frac{1}{bc},\frac{1}{ca},\frac{1}{ab}$ are also in $A.P$

Hence, this is the answer.
