the sum of the non - prime numbers between 10 and 20 , non - inclusive , is
"sum of consecutive integers from 11 to 19 , inclusive = = = = > ( a 1 + an ) / 2 * # of terms = ( 11 + 19 ) / 2 * 9 = 15 * 9 = 135 sum of non - prime numbers b / w 10 and 20 , non inclusive = = = > 135 - 60 ( i . e . , 11 + 13 + 17 + 19 , being the prime # s in the range ) = 75 answer : b"
