The smaller of two consecutive numbers is x + 3. Find the sum of the two numbers.

x+3. is the first num

x + 4 is the second num

the sum is 2x + 7

2x + 7

Difference is 1

Step-by-step explanation:

Consecutive numbers are numbers that increase with a steady difference.

For example; 1, 2, 3 all increase with a difference of 1 (2 = 1 + 1; 3 = 2 + 1) and so on.

If the smaller of two consecutive numbers is x + 3, that means the other number which should be bigger is x + 4

Therefore the sum of both numbers is (x + 3) + (x + 4) = 2x + 7.

Their difference is (x + 4) - (x + 3) = 1

And subtracting their sum from x + 8 gives (x + 8) - (2x + 7) = x + 8 - 2x - 7 = - x + 1.
