Let's call the number "x."
The expression "half the sum of a number and 26" can be represented as (1/2)(x + 26).
According to the problem, this expression is equal to 15, so we can form the equation:
(1/2)(x + 26) = 15
To solve for x, we can multiply both sides of the equation by 2 to remove the fraction:
x + 26 = 30
Subtracting 26 from both sides of the equation gives us:
x = 4
Therefore, the number is 4.
