You can use the formula for an arithmetic sequence for this. In this case, the calculation is (1 + 50) x 50 / 2.

if you add all the numbers up and dived them by the numbers of numbers
The numbers are 150, 152 and 154.
You add up all of your numbers then divide that by the number of numbers you have. That will be the average.
1, 3, 5, 7, etc. (just add two at a time).
What you have to do is you add up all the numbers then you divide by the number of numbers. ex. Say you have the numbers 45,56,39 and 35 you add them all up 45+56+39+35=175 then you divide 175/4(because there is 4 numbers)=43.75
