Let n be the step number,

Step 1 has 2 squares, step 2 had 6 squares, step 3 has 10 squares.

The equation which satisfies this situation is n^{2} + 1.

When we plug in n = 1, we get 1^{2}+1 = 2. These are the number of squares in step 1.

When we plug in n = 2, we get 2^{2}+1 = 5. These are the number of squares in step 2.

When we plug in n = 3, we get 3^{2} + 1 = 10. These are the number of squares in step 3.
