vesna_86 [32]

To understand the algebra, go through the following equations below:

  • First the thing to note is that the top square is the square of the bottom square: Stage 1: 1 & 1^{2} , stage 2 = 2 & 2^{2}, stage 3 = 3 & 3^{2}
  • Second image: Just add the two values above to get the total of tiles needed.  For stage 5: 5 + 5^{2} = 30, Stage 12: 12 + 12^{2} = 156

Part B

  • First equation : y = n^{2} + n
  • second equation: y = n + (n*n)
