Question

try to write an equation to describe the relationship between the stage number N and the number of squares S.

Answer 1

Let's first identify the number of squares in each stage:

Stage 1: 7 squares.

Stage 2: 14 squares.

Stage 3: 21 squares.

If we notice the sequence, we notice that it increases by 7 per stage, therefore:

Stage N: N*S

Where S is always equal to 7.

Foe example, in the stage 4:

Stage 4: 4*7 = 28 squares.

The equation is:

7*N
