Question

The sum of 4 consecutive even numbers is greater than that of three consecutive odd numbers by 81

Answer 1

even numbers x - 2,   x,   x+2,   x+4

Odd numbers x-1,  x+1,   x+3

x - 2 + x + x + 2 + x + 4  = x - 1 + x + 1 + x + 3 + 81

4x + 4 = 3x + 3 + 81

x  = 84 - 4 = 80

So Even numbers 78, 80, 82, 84

Odd numbers 79, 81, 83
