- We need to find the common difference of the Arithmetic sequence using Nth term formula of an arithmetic Sequences.
Nth term = A + (N-1).D
Using this Nth term of an arithmetic Sequence formula we can get the common difference.
In this question we have got two situations equating both situations, we can easily cut the equal parts that is first term(a) then we will be left with the common difference only that we need actually.
