Answer 1

hey buddy here is your answer by UDIT

it is clear that in option B common difference is 1-(-2)=3 =4-1=3

so common differnce is constant i.e 3


so B forms an AP

Answer 2

It is clear that in option B common difference is 1-(-2) =3 =4-1=3.

So common difference is constant i.e 3. so B forms an AP.

In an arithmetic sequence, it is offering the first and sum includes term before consider for constant values.

It includes basics and there still many sequences have to be evaluated.
