Find four consecutive odd numbers which add to 80. Give the numbers smallest to largest
80 / 4 = 20
Take it from there.

----
4 n + 12 = 80
4 n = 68
n = 17
17, 19 ,21 ,23
thx helped me lots :)
Correct
To find four consecutive odd numbers that add up to 80, we can use algebra. Let's assume that x represents the first odd number. Since the four numbers are consecutive, the next three odd numbers would be x+2, x+4, and x+6.
The sum of these four numbers can be expressed as:
x + (x+2) + (x+4) + (x+6) = 80
Simplifying the equation:
4x + 12 = 80
Next, we isolate the x term by subtracting 12 from both sides of the equation:
4x = 68
Finally, we divide both sides of the equation by 4 to solve for x:
x = 17
Now we have the first odd number as 17. The next three consecutive odd numbers are:
17 + 2 = 19
17 + 4 = 21
17 + 6 = 23
Therefore, the four consecutive odd numbers that add up to 80, from smallest to largest, are: 17, 19, 21, and 23.
