IS the sequence right?

Question

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

Answer 1

A pattern which exist is given $a<b<c$ three integers which are all different, the value in the middle is $b\times c - a^2$

Answer 2

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