The average of three consecutive odd numbers is -3. Find the largest number.
-
the average would be the middle
(?),-3,(?)
three consecutive odd numbers:
(-5),-3,(-1)
soory,
largest number would be -1

-
The numbers are -5, -3 and -1
The largest is -1

If you REALLY need an equation:
Let the numbers be "x - 4", "x - 2" and "x". (Note that the largest of the three is "x". Check for "oddness" at the end.)
Average = ((x - 4) + (x - 2) + x)/3
= (3x - 6)/3
= 3(x - 2)/3
= x - 2
The average is -3, so:
x - 2 = -3
Therefore x = -1
