Answer 1

Answer:

b) Of which we have to find but

But I will give an example

If an question is

Find the 27th term of the following A.P.

Find the 27th term of the following A.P.9, 4, −1, −6, −11,

so, the answer will

A=9,n=27

d=4−9

=−5

Putting the values in below formula

a27=a+(n−1)d

a27=9+(27−1)×−5

=9+(−130)

=9−130

=−121

So, you can do like these
