Answer 1

Answer:

sum of 8 terms to sum of 19 terms

8/2(2a+7d)=19/2(2a+18d)

8(2a+7d)=19(2a+18d)

38a-16a+342d-56d=0

22a+286d=0

22(a+13d)=0

a+13d=0

which is 14th term

Answer 2

Answer: sum of 8 terms to sum of 19 terms

8/2(2a+7d)=19/2(2a+18d)

8(2a+7d)=19(2a+18d)

38a-16a+342d-56d=0

22a+286d=0

22(a+13d)=0

a+13d=0

which is 14th term
