Question

Here is a pattern of squares. Z Step 1 Step 2 Step 3 Which equation represents the relationship between the step number and the number of squares in the pattern. n²+n n+n n² + 2 n²-2

Answer 1

Number of squares

when n =1, the number of squares =2,

when n = 2, the number of squares = 6,

when n= 3, the number of squares = 12,

From the list of the equations, the one that satisfies the relationship between the step number and the number of squares in the pattern = n^2 + n
