Question

If the nth term of AP 1,7,13.... is same as the nth term of 69,68,67.... find n​

Answer 1

Answer:

simply write

as nth term of 1st Ap is

=1+6(n-1)....(I)

similarly

nth term of 2nd

Ap is

69-(n-1)...(2)

now from (1)and(2)

1+6(n-1)=69-(n-1)

7(n-1)=68

n-1=68/7

n=75/7

no possible n such that nth term of both the Ap will be equal.
