Question

find the average of the 7 consecutive composite numbers below 100

Answer 1

Hey there!

Prime numbers between 1 to 100 are:

2,3,5,7,11,13,17,19,23,29,31,37, 41,43,47, 53,59,61,67,71,73,79,83,89, 97.

∴ Remaining Numbers (Composite) numbers are (they are also Consecutive):

90,91,92,93,94,95 and 96.

Thus,
Their Average = 90+91+92+93+94+95+96/7

                       = 651/7

                       = 93

Hence,
The average of the 7 consecutive composite numbers below 100 is 93.
