Answer :

As we know, nth term in A.P. is a + (n-1)d

Where, a is first term

n is Nth term

d is difference between terms

Given in one sequence, a1=63 and d1=2

In the other sequence, a2=3 and d2=7

Given nth term of both A.Ps are equal

So, a1+(n-1)d1=a2 +(n-1)d2





Conclusion: Therefore, for n = 13 it is equal.
