It's not clear what's under the radical.

Because a square root is always non-negative, the equation is true as long as (2x-1) is non-negative.

The four largest integer values of (2x-1) that are NOT non-negative are -1, -2, -3, and -4.

The sum of those four values is -10; the average is -10/4 = -2.5.
