There’s one smaller number and one bigger number when looking at the middle number. We need to make equations for these numbers.
X= middle number
X-1= smaller number
X+1= bigger number
We need to add all of these numbers together and make it equal 102.
X+X-1+X+1=102
Now add like terms
3x= 102
Divide.
102/3=34
34 is the middle number, but we need to check. The list would be 33, 34, and 35.
Let’s add them all together.
33+34+35=102
So, the middle number of the set is 34.
