Question

In a set of four consecutive positive integers, the smallest integer is less than half the largest integer. what is the largest integer that could be in the set?

Answer 1

Let integers be  x, x+1, x+2 and x+3

x < 0.5(x + 3)

x <  0.5x + 1.5

0.5x < 1.5

x < 3

so x = 2  given that they are positive integers

so the largest integer that could be in the set is 2 + 3  = 5  answer
