29 - 28 = 1 141 + 1 = 142
It is (36+28)-15 = 49
N = -12 + 8*(17+28) = -12 + 8*45 = -12+360 = 348
The sum of the prime numbers that are greater than 3 and less than 28 is: 95

A perfect number is an integer, the sum of whose integral factors, including 1, but excluding itself, is equal to itself. In other words, when the sum of a number's proper factors equals itself, it is called a perfect number. That means that if you add all of any given number's factors (including 1, but not itself), you get that number. 6 Factors: 1, 2, 3, 6 Sum of factors less than itself: 1 + 2 + 3 = 6 28 Factors: 1, 2, 4, 7, 14, 28 Sum of factors less than itself: 1 + 2 + 4 + 7 + 14 = 28
14 is deficient. It is less than the sum of it's divisors. In mathematics, a deficient number or defective number is a number n for which σ(n) < 2n. Here σ(n) is the sum-of-divisors function: the sum of all positive divisors of n, including n itself Proof.. divisors of 14 are 1,2, and 7 and 14. Now, 2n=28 and and the sum the all the divisors including 14 is 24<28
