Question

Identify the harmonic progression.

• A. $1,\frac{1}{2},\frac{1}{3},\frac{1}{4}..$
• B. $1,2,3,4,\mathrm{5.....}$
• C. $1,-1,1,-1,\mathrm{1...}$
• D. $1,\frac{1}{2},\frac{1}{2},\mathrm{1..}$

Answer 1

The correct option is A $1,\frac{1}{2},\frac{1}{3},\frac{1}{4}..$

Harmonic progression is a sequence formed by the reciprocal of arithmetic progression.
$1,\frac{1}{2},\frac{1}{3},\frac{1}{4}..$ is a harmonic progression.
