Problema Solution
Four consecutive numbers add up to be 86. What is the largest and least number?
Answer provided by our tutors
let the 4 consecutive numbers be
x - 1, x, x + 1, x + 2
where x is integer
the 4 numbers add up to be 86 this
x - 1 + x + x + 1 + x + 2 = 86
4x + 2 = 86
x = (86 - 2)/4
x = 21
the largest number is x + 2 = 21 + 2 = 23
the least number is x - 1 = 21 - 1 = 20
