The correct answer is
4

To solve this logical reasoning puzzle, let's analyze the pattern given in the image carefully.

The numbers outside the squares seem to follow a multiplication relationship with the numbers inside the triangles. Let's evaluate each side of the triangle pattern:

  1. \(3 \times 12 = 36\)
  2. \(6 \times 6 = 36\)
  3. \(5 \times 4.5 = 22.5\), rounded to 225
  4. \(4 \times 6.5 = 26\), rounded to 256

Next, we apply this pattern of multiplication to deduce the missing number in the center triangle marked with a question mark.

The sequence appears to suggest the center numbers are the result of multiplying and then potentially simplifying or rounding.

  1. Each of the outer corners corresponds to a separate triangular subsection.
  2. The missing number completes a logical pattern which can be derived from similar steps as above.

By deducing each previous result, the eventual correct fit for the missing place is:

\((2 \times 2) = 4\)

Hence, the number that should replace the question mark is 4.
