Question

The first term of a harmonic is $\frac{1}{7}$ and the second term is $\frac{1}{9}$. The ${12}^{th}$ term is

• A. 1/19
• B. 1/29
• C. 1/17
• D. 1/27

Answer 1

The correct option is B

1/29

Here first term of A.P. be 7 and second be 9, then ${12}^{th}$ term will be 7 + 11 $\times$2 = 29

Hence ${12}^{th}$ term of the H.P. be $\frac{1}{29}$.
