Question

If 15 times the 15 term is equal to 18 times the 18 term. Find the 33rd term
Of the ap

Answer 1

33rd term = a + 32d

and

15(a+14d)=18(a+17d)

5(a+14d)= 6(a+17d)

5a + 70d = 6a + 112d

a= -42d

a+42d=0

a+ 32d +10d= 0

a+(32+10)=0

a= -42

d= 1

33rd term = -10 d

= -10.

hey plz tell if the question is correct I think that there should be ..find the 32 Nd term
