Triangular numbers - Roots with bases other than 1

  • #1
Not sure where this should go, but - How would you calculate the square root of a triangular number with a base other than 1? For example, 2, 6, 12, 20 (Base 2).

Would rather have help to figure it out than the actual formula.

Never mind - Realized I can just divide the number by the base and use the normal formula.
