It is 50.
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
Wiggle x 5 + 7 -7 % of 100
(n+1)/2 = 10.5
The average of 33 consecutive whole numbers is 58, what is the smallest of these whole numbers? The answer is 42

It is 50.
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
The average need not be a whole number, so just use the answer which the calculation yields.
Wiggle x 5 + 7 -7 % of 100
Elements also possess isotopes. So their average atomic mass is rarely whole number.

(n+1)/2 = 10.5
If the 33 numbers are consecutive then 58 must have 16 lower and 16 higher so the lowest is 58 - 16 ie 42
