Question 53223
To set up the problem begin by saying n is your smallest integer.  And so with 4 consecutive integers you would have the following: {{{n}}}, {{{(n+1)}}}, {{{(n+2)}}}, and {{{(n+3)}}}.  The next thing you have to worry about is the next part of that sentence. The greatest integer in the set is twice as big as the smallest integer.  When written out it looks like this: {{{(n+3) = 2n}}}.
Now we solve for n.  To do that 1 n from each side to get {{{3 = n}}}. Since the set of integers have to positive then {3, 4, 5, 6} is your set.

Hope this helps.
