Each of these results in 280: 1 x 280, 2 x 140, 4 x 70, 5 x 56, 7 x 40, 8 x 35, 10 x 28, 14 x 20
2 numbers that can go into 280 are 2 and 8 but there are way more though.
(40+200)+(5+80)
Double means multiply by '2' or another word is 'twice'. 280 x 2 = 560

The middle number for 150 and 280 is 215. Here's how you work it out: Add the two numbers together which makes a total of 430. Then you divide the number by the number of numbers you added together to give you your answer.
Let the numbers be 'm' & 'n' Hence m + n = 2 mn = - 280 It follows that m = 2 - n Substitute (2 - n)n = -280 Multiply out the brackets 2n - n^2 = -280 n^2 - 2n - 280 = 0 It is now in Quadratic form. Either use the Quadratic Eq'n or 'Complete the Square'. n^2 - 2n = 280 (n - 1)^2 - (-1)^2 = 280 (n - 1)^2 = 281 Square root both sides n -1= sqrt(281) n = 1 +/- sqrt(281)
280 Mean, which is the same as average, is the sum of the numbers divided by the quantity of the numbers: (280 + 280 + 250 + 320 + 270) ÷ 5
Each of these results in 280: 1 x 280, 2 x 140, 4 x 70, 5 x 56, 7 x 40, 8 x 35, 10 x 28, 14 x 20
Easy just divide 280 / 175 then multiply by 100 = 62.5%
