If you use the first four squares to set up a system of equations with the outer numbers as coefficents of 4 unknowns and the middle numbers as the RHS constant terms you can solve the system. Use this result find the value for 'a' missing number. I get -14.8421.

I doubt this is what the author is looking for.

I used the first square to get the last square.
14-3=11
14-5=9
14-8= 6
14-10=4
