In the given problem, we are given the sequence with the nth term ().
We need to show that these sequences form an A.P
Now, to show that it is an A.P, we will first find its few terms by substituting
Substituting n = 1, we get
Substituting n = 2, we get
Substituting n = 3, we get
Further, for the given sequence to be an A.P,
Common difference (d)
Hence, the ...
