If a1, a2, ….,an forms an AP then the nth term of an AP is given by : an = a + (n - 1) × d, where a is the first term and d is the common difference.
Calculation:
Two digit numbers which are divisible by 4 are:
12, 16, 20, ..., 96 forms an AP with,
First term (a) = 12,
Common difference (d) = 4 and,
nth terms (an) = 96.
⇒ an = a + (n - 1) × d = 96
⇒ 12 + (n - 1) × 4 = 96
∴ n = 22Last updated on Jul 8, 2025
