Solution
Correct Answer: Option B
Looking at the first two trees:
- Tree 1: Nodes 2 and 4 → Result 20
- Tree 2: Nodes 3 and 9 → Result 90
After analyzing possible patterns, I found that:
- 2² + 4² = 4 + 16 = 20 ✓
- 3² + 9² = 9 + 81 = 90 ✓
Therefore, the pattern is: square each number and add them together.
For the third tree with nodes 1 and 5:
1² + 5² = 1 + 25 = 26
The answer is B) 26.
