Question

the sum of first 10 terms and the sum of first 100 terms of an ap are 100 and 10 respectively then find the sum of first 110 terms​

Answer 1

s10=100 and s100=10

s10=100 and s100=10(2a+9d)=20

s10=100 and s100=10(2a+9d)=20(2a+99d)=1/5

s10=100 and s100=10(2a+9d)=20(2a+99d)=1/5by eliminating method apply
