4 1x1 squares + 1 2x2 square = 5 squares
9 1x1 squares + 4 2x2 squares + 1 3x3 square = 15

Are individual squares of equal size? Because they don't appear to be.

12

work:

n = number of unit segments
x = number on the right

n=(x+1)*2

So in the first one n=12 and x=5 and the second one n=24 and x=11.

11 is my answer
n =

I tried Lagrange interpolation and came up with 5. Thank me later.

oops 14 rather

still better than all these pseuds doing math until they're up their own ass instead of seeing the obvious

Its the number of even degree vertices.
So the bottom is 8.

(Number of vertical lines + Number of horizontal lines) - 1

3 + 3 - 1 = 5
4 + 4 - 1 = 7

No, wait!

I changed my mind.

It's (Number of small squares + 1)

4 + 1 = 5
9 + 1 = 10
