As a sequence, you multiply by 4 and add 1.

To find two numbers that add up to 4 and multiply to -21, we can set up a system of equations. Let's call the two numbers x and y. We have the equations x + y = 4 and x * y = -21. By solving these equations simultaneously, we can find that the two numbers are 7 and -3. This is because 7 + (-3) = 4 and 7 * (-3) = -21.

If you've written that correctly, there aren't two whole numbers that satisfy those conditions. -20 and -5 add to -25, but multiply to 100. -25 and 4 multiply to -100, but add to -21.

There are no two real numbers that do, but the complex numbers (2 + i) and (2 - i) will.If you want two numbers that multiply to negative 5 and add to positive 4 then: -1 and 5If you want two numbers that multiply to negative 5 and add to negative 4 then: 1 and -5
