Answer:
Option A is correct not arithmetic
Explanation:
We have given terms [tex]\frac{1}{2},{1}{3},{1}{4}[/tex] 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.
[tex]d=a_2-a_1[/tex]
we can see the difference between [tex]\frac{1}{3}[/tex] and [tex]\frac{1}{2}[/tex] is [tex]\frac{-1}{6}[/tex]
Whereas, the difference between [tex]\frac{1}{4}[/tex] and [tex]\frac{1}{3}[/tex] is [tex]\frac{-1}{12}[/tex].
