Heya!!

Given A.P is

24 , 21 , 18 , 15 , ......,0 , ist negative term

COMMON THOUGHT

before reaching ist negative term we must pass through 0th term

Let that 0th term be x

Tx = a + ( x - 1 ) d

Tx = 0 , a = 24 and d = -3

0 = 24 + ( x -1 ) × -3

x - 1 = 8

x = 9

So, the ist negative term is x + 1 term.

= 10

Have a nice day ahead.
