Answer 2

Given that : a = 27, d = 24-27 = -3 and

$S_{n} = 0$

Now, As we know that from the formula of sum of the A.P. :

$S_{n} = \frac{n}{2} [2a + (n - 1)d] \\ \\ = > 0 = \frac{n}{2} [2 \times 27 + (n - 1)( - 3)] \\ \\ = > n(54 - 3n + 3) = 0 \\ \\ = > 57 - 3n = 0 \\ \\ = > 3n = 57 \\ \\ = > n = \frac{57}{3} = 19$

So, the terms in A.P. will be 19
