EasyPython

Problem

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
