Question

an= 3+an
find the sum of
S24​

Answer 1

Answer:

The nth term is an=3+2n so by using this we can find the value of terms like a1=5,a2=7,a3=9

and a24=51

now the first term is 5 and the last term is 51 and the difference is 2

by using the formula for sum of n terms i. e

sn =n/2(2a+(n-1)d)

so s24=24/2(10+23*2) i. e 672 ans.
