If we continue making the spiral below until we reach 83 what number will appear directly to the left of 83?

83 is quite close to 81. 

At 81, there will be a 9 by 9 square, meaning at 83, it will be 9 less than 83. 

83 - 9 = 74

I hope that's correct.

Oh no, it looks like we have different answers. 

I'm rechecking and my answer is wrong. 

 

9^2-7^2 = 32

32+1 = 33

83 - 33 = 50

 

Yep, 50 is correct. 

Thank you to geno for helping me get the right one. :))

I think that it is  50.

 

Now, draw out the spiral and tell us which one of us is correct ...
