Answer:
Option A is correct not arithmetic
Explanation:
We have given terms \(\frac{1}{2},{1}{3},{1}{4}\) these terms are not an arithmetic progression because
Arithmetic progression is the sequence of terms in which difference between successive and proceeding terms is same.
\(d=a_2-a_1\)
we can see the difference between \(\frac{1}{3}\) and \(\frac{1}{2}\) is \(\frac{-1}{6}\)
Whereas, the difference between \(\frac{1}{4}\) and \(\frac{1}{3}\) is \(\frac{-1}{12}\).
