Question

Which term of A.P; 4,9, 14, ... is 24?​

Answer 1

Answer:

Ans is 5 that is the 5 term of this AP is 24

Answer 2

Answer:

In the given A. P.

Common difference = ( a2 - a1)

= ( 9 - 4 )

= 5

First term = 4

we know An = a + ( n - 1 ) d

and An = 24

24 = 4 + ( n - 1 ) 5

24 = 4 + 5n - 5

24 = 5n - 1

24 + 1 = 5n

25 / 5 = n

n = 5

Thus the 5 th term of this A. P. will be 24.
