Perfect numbers are numbers which equal the sum of their divisors. There are two numbers which fulfill this classification which are less than 30:
1 + 2 + 3 = 6
1 + 2 + 4 + 7 + 14 = 28
Perfect numbers can be calculated with the following formula:
2n*(2(n+1)-1)
For example, the first perfect number is: 21*(22-1) = 6
The second perfect number is: 22*(23-1) = 28

When is the sum of two integers less than the difference?
When the integers are negative.
The sum of two consecutive integers is -6943 what are the integers?
Two consecutive integers will be 0.5 more and 0.5 less than the quotient of their sum divided by 2. The given sum of the two consecutive integers divided by 2 is -3471.5, so the two consecutive integers are -3472 and -3471.
The sum of two consecutive integers is less than 55?
Let the two consecutive integers be n and n+1. Then, n + (n + 1) < 55 2n + 1 < 55 2n < 55 - 1 : 2n < 54 n < 27 The Inequality Statement can therefore be modified to show that for two consecutive integers to be less than 55 then the smaller integer must be less than 27.
The sum of three consecutive odd integers is -273 what are the integers?
Divide the sum of the three consecutive odd integers by 3: -273 /3 = -91. The smallest of these integers will be two less than -91 and the largest will be two more than -91, so the three consecutive odd integers will be -89, -91, and -93.
The sum of two consecutive even integers is 90.find the numbers?
Divide the sum of the two consecutive even integers by 2: 90/2 = 45. The smaller of these integers will be one less than 45 and the larger will be one more than 45, so the two consecutive even integers will be 44 and 46.
