Question

for what value of n,are n th term of APs:63,65,67.........and 3,10,17,........equal?

Answer 1

In the question, we have two AP’s and have to find the nth term when both AP’s will have the equal value.

For this we have to use the equation of nth term.

63 + ( n – 1) * 2 = 3 + ( n – 1 ) * 7

5 * ( n – 1 ) = 60

n – 1 = 12

n = 13
