Question

find the 24th term of the AP 12 16 20 24​

Answer 1

Hello !!

Find the common difference.

d = (An - Ak)/(n - k)

d = (16 - 12)/(2 - 1)

d = 4/1

d = 4

Find the 24th term.

An = A1 + (n - 1) × d

A24 = 12 + (24 - 1) × 4

A24 = 12 + 23 × 4

A24 = 12 + 92

A24 = 104

Final result : 104 is the 24th term.

I hope I have collaborated !
