IS the sequence right?

Question

enter image description here

What i think is that, the sequence isn't correctly formulated.

I have tried like this 7x5-9=35

2x3-1=5

8x6-4=44

4x5-9=?=11

My understanding: multiply the two largest and subtract the square of the smallest. Hence, 29. — , Jun 19 '14 at 15:48

Hint: \begin{align*} 26 &= 7\times 5 -3^2 \\ 5 &= 2\times 3-1^2 \\ 44 &= 8\times 6-2^2 \end{align*}
