Find the value of the following expression: 3^2 + 8^2 + 13^2 + 18^2 + .... + 98^2.
67630 becuase it is 3+64+169+...+9604 anyways heres the python code to solve it " print( 3**2+8**2+13**2+18**2 +23**2+28**2+33**2+38**2+43**2+48**2+53**2+58**2+63**2+68**2+73**2+78**2+83**2+88**2+93**2+98**2.) "
sumfor(n, 1, 20, (5*n - 2)^2) = 67,630
