Question

which term of an a.p. -7,-4,-1,2,.... is 101?​

Answer 1

Answer:

Step-by-step explanation:

-7, -4, - 1,2, .....

a = -7,  d = -4 - (-7) = 3

The nth term of an AP is given by Tₙ = a + (n - 1 )d

=> 101 = - 7 + (n - 1)3

=> 3n - 3 = 108

=> 3n = 111

=> n = 111/3 = 37.

Thus it is the 37th term.
