Question

If 12,16,20,24,………… are in A.P then find 24th term of this A.P​

Answer 1

Answer:

The A.P. 12,16,20,24

Here a=12,d=16−12=4,t

24

=?

t

n

=a+(n−1)d

∴t

24

=12+(24−1)4 (∵n=24)

=12+23×4

=12+92

∴t

24

=104

Thus 24

th

term of the A.P. is 104.

Answer 2

Step-by-step explanation:

The given A.P is 12,16,20 and 24

1st term (a) = 12

Common difference (d) = 16-12=4

T= a+(n+1)d

= 12+(n+1)4

=12+4n+4

=16+4n

T24 = 16+4×24

=16+96

=112
