So what you want to say is 216/4, to find 1/4 of 216. 216 / 4 = 54
So you know that therefore, since 1/4 + 1/4 + 1/4 + 1/4 = 1, 54 + 54 + 54 + 54 must equal 216.
So basically what you can say is,
x - 3 + x - 1 + x + 1 + x + 3 = 216
This would make them consecutive odd integers, but since the addition and subtractions cancel out, it would still make it equivalent.
Or basically:
(54 - 3) + (54 - 1) + (54 + 1) + (54 + 3) = 216
51 + 53 + 55 + 57
Those four integers would add up to 216, and would therefore be the four consecutive odd integers.
