The first 9 positive odd integers are placed in the following 3 by 3 grid in such a way that the sum of the numbers in each row, column, and main diagonal is the same. Four of the numbers are shown and the other five numbers are represented by the letters A, B, C, D, and E. Determine the values of A, B, C, D, and E.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
