To find five numbers that multiply to 280, one possible combination is 1, 2, 4, 5, and 7. When multiplied together, these numbers yield 1 × 2 × 4 × 5 × 7 = 280. There are other combinations as well, but this set fulfills the requirement.
To find out what must be added to 280 to make 10,000, you can subtract 280 from 10,000. This calculation gives you 10,000 - 280 = 9,720. Therefore, 9,720 must be added to 280 to reach 10,000.

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
Oh, dude, you're hitting me with some math vibes. So, the numbers that multiply to equal 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, and of course, 280. Like, that's the whole squad right there.
