good evening! Can someone please answer this, ill give you brainliest and your earning 50 points. Would be very appreciated.

Answer:
From inspection of the diagram, the pattern is:
Step 1: 1² + 1
Step 2: 2² + 2
Step 3: 3² + 3
Let x = step number
Let y = total number of squares
Therefore, the equation that represents the relationship is:
y = x² + x
x² relates to the large square made up of small squares (top part of the image of each step)
x relates to the rectangle of small squares (bottom part of the image of each step)
y is the total number of small squares in the image of each step.
The pattern is
More simply
So for an integer n
#b
n² is pair of boxes at top side
n is boxes underneath
