Question

Find three consecutive integers such that the sum of the first integer, half the second integer and four times the third integer is -30

Answer 1

x + 0.5(x + 1) + 4(x + 2) = -30  (where x is the lowest integer)
x + 0.5x + 0.5 + 4x + 8 = -30
5.5x =   -38.5
x = -7

The required integers are -7, -6 and -5 (answer).
