f(n) = (n² + n) / 2
f(1) = (1² + 1) / 2 = 1
f(2) = (2² + 2) / 2 = 3
f(3) = (3² + 3) / 2 = 6
f(4) = (4² + 4) / 2 = 10
f(5) = (5² + 5) / 2 = 15
f(6) = (6² + 6) / 2 = 21

What is the nth term for 15 21 27 33 39?
A single number, such as 1521273339 does not define a sequence. There is no nth term for a signle number.
Can you find the nth term from the pattern 5 12 21 32?
The nth term is n2 + 4n.
