Question

Is 68 a term of the AP:-7,10,13......….…..……? ​

Answer 1

Answer:No 68 is not a term of given AP

Step-by-step explanation:

a = 7

d = 3

Let 68 is the nth term of ap

an = 68

a+( n-1)d=68

7+(n-1)3= 68

n-1 = (68 -7)/3

n-1 = 61/ 3

n = 61/3 + 1

n = 64 /3

n can never be in negative

So 68 is not in AP
