Question 1114754
<br>
Take the first suggestion at the end of the response from MathTherapy lightly.  While it is good practice, especially for beginning students, to start your solution with "let x = ...", it is not NECESSARY.<br>
His last statement you should ignore completely, as it is just plain wrong.  There are always many ways to solve a problem; the solution from tutor josgarithmetic is perfectly good.<br>
One part about tutor josgarithmetic's response that is worthwhile is his use of n-1, n, and n+1 as the three consecutive integers, instead of x, x+1, and x+2.  Although in this problem it didn't simplify the required arithmetic significantly, it can often be very advantageous -- in terms of the amount of work required to solve the problem, and in terms of the level of difficulty of the work -- to let your variable be the middle number instead of the first.
