What is the average (arithmetic mean) of all the multiples of ten from 10 to 180 inclusive?	Pick one:
A) 90  B) 95  C) 100  D) 105  E) 110
10 and 190 inclusive would mean there are 19 terms.   No need to add up all the terms and further divide by 19 since the terms are evenly spaced in ascending order from 10, 20, 30........180   The middle term is the average which is the tenth term = 90   90 is the answer.
