    Kid has a math homework I can't figure out. What are the next 3 numbers in this sequence?

    2, 12, 36, 80

    [Teacher rarely makes typos, this is not meant to be a trick question, etc. This is late middle-school, so leave your fancy trig-and-beyond at home.]

      @arclight @shriramk
      The correct answer is “Let’s consult the OEIS”

      @shriramk I hate these problems because there's always some implied or assumed formula. The unsatisfying (but IMO correct) answer is: As presented, there is not enough information to solve this problem.

      One solution they may be looking for is:
      2, 12, 36, 80, 150, 240, 356, ...
