Sequence Pattern Problem | Dataford Interview Questions

Solve a basic sequence pattern: 2, 6, 12, 20, X. What is X?

Implement next_term(sequence) to return the next value in a sequence following this pattern. The input is a list of integers beginning with 2, 6, 12, 20, and the output is one integer. For the given sequence, the expected result is 30.

Constraints

4 <= len(sequence) <= 100
sequence begins with [2, 6, 12, 20]
The sequence follows term n = n * (n + 1)
Return the single next integer

Function Signature

def next_term(sequence):
