Answer:
x+3. is the first num
x +4 is the second num
the sum is 2x +7
Answer:
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.
