8 and 6 have a difference of 2 and a sum of 14.
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
They are: 5 and 14
The numbers are 12 and 14.
Let's name the first number x and the next number x + 1. So, x^2 - (x + 1)^2 = x^2 - (x^2 + 2x + 1) = x^2 - x^2 - 2x - 1 = - 2x - 1 = -(2x + 1) Thus we can say that, the difference between the squares of two consecutive numbers is equal to the opposite of their sum (means it is their sum, but as a negative number). Let's do some examples: 2, 3; 2 + 3 = 5 2^2 - 3^2 = 4 - 9 = -5 ( 5 and -5 are opposite numbers, and 5 is the sum of 2 and 3) 13, 14; 13 + 14 = 27 13^2 - 14^2 = 169 - 196 = -27 (27 and -27 are opposite numbers, and 27 is the sum of 13 and 14)
8 and 6 have a difference of 2 and a sum of 14.
The two numbers are 21 and 7.
25 & 14
The two numbers are 10 and 4
6 and 8
It is 14 and 6.
7 & 14
The numbers are 15 and 1
14 and 10
15 + 1 = 16 sum 15 - 1 = 14 difference
25 and 11
25 and 14.
