Question

If nth terms of the APs 63, 65, 67, ... and 3, 10, 17, ... are equal, the n is: *​

Answer 1

Answer:

hope this helps u

Step-by-step explanation:

Let the 1st AP be A =63,65,68.....

Let the 2nd AP be B = 3,7,17......

For A , common difference is : 65-63 = 2

For B ,common difference is : 10-3 = 7

Now Let the nth term be An and Bn respectively.

According to question

An = Bn

=> 63+(n-1)2 = 3+(n-1)7

=>60 + 2n-2 = 7n-7

=>65 = 5n

=> n = 13

Thus 13th term of both AP's will be same
