  • Pattern A: Step 3 has 10 dots. It grows by 3 dots at each additional step.
  • Pattern B: The total number of dots can be expressed by , n^{2}+2 where, n, is the step number.



For each pattern, draw a diagram of Step 0 to Step 3.

  • Pattern A: Since the pattern grows by 3 dots, and there are 10 dots in step 3, we have 1 dot at step 0, 4 dots at step 1, 7 dots at step 2, and 10 dots at step 3.
  • Pattern B: Since the dots follow a n^{2}+2 pattern where n is the step number, step 0 - 0^{2}+2 = 2, step 1 - 1^{2}+2 = 3, step 2 - 2^{2}+2 = 6, step 3 - 3^{2}+2 = 11
