Answer:
(n + 1)²
Step-by-step explanation:
note that 4, 9, 16, 25, 36 are square numbers
To generate the terms add 1 to the position n and square, that is
first term : n = 1 → n = 1 + 1 → 2² = 4
second term : n = 2 → n = 2 + 1 → 3² = 9
third term : n = 3 → n = 3 + 1 → 4² = 16
Hence n th term is (n + 1)²
