Answer:
Any value greater than 5:
x > 5
Step-by-step explanation:
The average of two numbers 'a' and 'b' is given by the formula:
Average = (a + b)/2
If the average between x and its successor (that is, x+1) is greater than 5, we have that:
(x + (x+1)) / 2 > 5
x + x + 1 > 10
2x > 9
x > 4.5
The value of x is an integer number, so x can be any number greater than 5:
x > 5
