Question

is 68 a term 0f ap7,10,13....?​

Answer 1

hey

an = a + (n-1)d

68 = 7 + (n-1)3

68 - 7 = (n-1)3

61/3 = n-1

n = 61/3 + 1

n = 64/3

therefore 68 is not a term of AP

Answer 2

here first term, a = 7

common difference, d = 10 - 7 = 3

let the nth term be 68

so 68 = 7 + (n-1)3

=> 61 = ( n - 1)3

=> n-1 = 61/3

=> n = 61/3 + 1 = 64/3

here n is not a natural number

so 68 is not a term of the ap
