Question

If a is first term of H.P and d is common difference of corresponding A.P, nth term of H.P is

• A.
• B.
• C. + (n - 1)d
• D. None of these

Answer 1

The correct option is B

A is first term of H.P.

The corresponding A.P. will have first term as $\frac{1}{a}$

$\therefore$ nth term of A.P. = $\frac{1}{a}$ + (n - 1)d

So, nth term of H.P. = $\frac{1}{\frac{1}{a}+(n-1)d}$
