problem

The 5×55\times 5 grid shown contains a collection of squares with sizes from 1×11\times 1 to 5×55\times 5. How many of these squares contain the black center square? [asy] fill((2,2)--(3,2)--(3,3)--(2,3)--cycle,gray(0.1)); for (int i=0; i<6; ++i) { for (int j=0; j<6; ++j) { draw((0,i)--(5,i),linewidth(0.7)); draw((j,0)--(j,5),linewidth(0.7)); };} [/asy]
Plain-text mathematical notation (without MathML)
The 5×5 grid shown contains a collection of squares with sizes from 1×1 to 5×5. How many of these squares contain the black center square?

[asy]
