Question

For what value of n, are the nth terms of two APs: 63, 65, 67, ... and 3, 10, 17,... equal? ​

Answer 1

Answer:

First term =63 and common difference =2, For second ap first term =3 and common difference =7

no of terms=a+(n-1)d

Step-by-step explanation:

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

63+2n-2=3+7n-7

61+2n=7n-4

61+4=7n-2n

65=5n

n=13
