Correct Answer: 13

Solution and Explanation

To solve the problem, analyze the pattern within the circle. Notice the arrangement of numbers in each section. We need to find the missing value denoted by ? in the center of the circle.

Look at each segment pairing: 

  • The top segment is 2 and 1, with the center as 1.
  • The right segment is 3 and 5, with the center as ?. Compute this:

Observe the pattern: The value in the center could be derived from a function of the two numbers outside.

Center Function Hypothesis: Since the center numbers are powers, apply that logic:

  • Calculate the values by either squares or consistent operations:
  • 4²=16
  • 36=6²

Match the characteristics:

Calculate: (3+5)/2=4, raising the result by 3 (from left) and 5 (right) starting with their averages:

Calculate: 4³=64.

Verify across the segments.

Conclusion:

Verify against expectations:

  • 4²=16 is perfectly aligned.
  • 36=6².

The pattern suggests computation is based on known values of each operation.
