1.	icnCiS6Check whether- 150 is a term of the AP:
Answer» For an AP 11, 8, 5, 2.... First term a = 11, Common difference d = 8-11 = - 3 Ley - 150 is nth term of an APThen,-150 = a + (n-1)d-150 = 11 + (n-1)*(-3)-161 = - 3n + 3n = 164/3n = 5.43 If - 150 is term of an AP then value of n should be positive integer. Which is not true in this case. Hence, - 150 is not a term of an AP

For an AP 11, 8, 5, 2.... First term a = 11, Common difference d = 8-11 = - 3

Ley - 150 is nth term of an APThen,-150 = a + (n-1)d-150 = 11 + (n-1)*(-3)-161 = - 3n + 3n = 164/3n = 5.43

If - 150 is term of an AP then value of n should be positive integer. Which is not true in this case.

Hence, - 150 is not a term of an AP
