What is the positive difference between the sum of the squares of the first 8 positive integers and the sum of the prime numbers between the first square and fourth square?  Answers.
A) 161 B) 162 C) 163 D) 164 E) 165
Forget conventional ways of solving math questions. In PS, IVY approach is the easiest and quickest way to find the answer.   the sum of the squares of the first 4 positive integers = 1^2 + 2^2 + 3^2 +...+8^2= 204   the sum of the prime numbers between the first square(=1) and fourth square(=16) = 2+3+5+7+11+13=
