Answer 2

Answer: 23rd term is 71

Step-by-step explanation:

Given,

the sum of first 45 term is a.p 3195

We have to find out the 23rd term using the formula,

Sn=n/2[2a+(n-1)d]

S45=45/2[2a+(45-1)d]=3195

S45=45[a+22d]=3195

=a+22d=71

23rd term=a+(n-1)d

=a+(23-1)d

=a+22d

23rd term=a+22d

=71

23rd term=71

Hence we get the solution  23rd term is 71
