Question

which term of the ap
-4,-1,2,....... is 101

Answer 1

Answer:

Step-by-step explanation:

Acc to the question A = -4 ; D = 3; an = 101

We have to use the formula

An = a + (n - 1)d

Substituting the values in the above formula

101 = -4 + (n - 1 )3

101 + 4 = 3n - 3

105 = 3n - 3

105 + 3 = 3n

108/3 = n

N = 36

Therefore 101 is the 36th term of the

AP.

Answer 2

Answer:

The given number 101 is 36th term of the given AP

Step-by-step explanation:

First term a=-4;

common difference d= second term- first term

                                     =-1+4

                                      =3.

The nth term of an AP

=a+(n-1)d

here the nth term is 101

first term a=-4.

common difference d=3.

101=-4+(n-1)×3

105=(n-1)×3

n-1=35

n=36

36thterm of the given AP is 101.
