Answer:
58 58 60 60 are the lengths of the sides
Step-by-step explanation:
It seems you just keep adding 3
-2; 1; 4; 7; 10; 13; 16; 19; 22; 25; 28; 31; 34; 37
37 is the fourteenth term.

This is the solution of the equation, where a=1, b=-5, c=7
So the discriminant is :
b^2-4ac=25-4*7= -3
The square root of -3 is non-real, this both solutions are non-real.
