For what value of n, are the nh terms of two AP\'s 63, 65, 67,.. and 3

1.	For what value of n, are the nh terms of two AP\'s 63, 65, 67,.. and 3, 10, 17,... equal
Answer» Good For AP^1 :- a = 63d = 2 For AP^2 :- a = 3d = 763 + (n-1) 2 = 3 + (n-1) 763 + 2n - 2 = 3 + 7n - 761 + 2n = -4 + 7n 61 + 4 = 7n - 2n 5n = 65n = 13 AP¹:63,65,67a=63d=65-63=2AP²:3,10,17a=3d=10-3=7Given,An=Ana+(n-1)d=a+(n-1)d63+(n-1)2=3+(n-1)763+2n-2=3+7n-761+2n=7n-461+4=7n-2n65=5nn=13
