Question

5 consecutive squared whole numbers added together...
the sum of the first three equal the last two like
1squared + 2squared + 3 squared = 4 squared + 5 squared

wat is the answer?

Answer 1

x^2 + (x + 1)^2 + (x + 2)^2 = (x + 3)^2 + (x + 4)^2
x^2 -8x -20 = 0
(x + 2)(x - 10) = 0
x = 10, 11, 12, 13, 14

Answer 2

x*x + (x+1)*(x+1) + (x+2)+(x+2) = (x+3)*(X+3) + (x+4)(x+4)
