Hello !
Here is your answer !
9th term in an AP = a + 8d
15th term in the same AP = a + 14d
24th term = a + 23d
9(a+8d) = 15(a+14d)
9a + 72d = 15a + 210d
6a +138d = 0
a + 23d = 0
Hope it helps

☸ Required Answer is :-
Let the First Term of A.P = a
Nd the Common Difference = d
So, nth term of any A.P = a+(n-1)d
✔ 9th term of A.P = a+8d
✔ 15th term of A.P = a+14d
✔ 24th term of A.P = a+24d
A.T.Q
➡ 9(a+8d) = 15(a+14d)
➡ 9a+72d = 15a+210d
➡ 15a-9a +210d-72d =0
➡ 6a + 138d =0
by taking out 6 as common we get,
➡ a+24ad =0
Hence, the 24th term of A.P is Zero.
