Find the missing number: $23 : 125 :: 31 : ?$
The question presents a number analogy: 23 : 125 :: 31 : ?. We need to find the relationship between the first pair of numbers (23 and 125) and apply it to the second number (31) to find the missing number.
Finding the Pattern
- Consider the first number, 23. The sum of its digits is $2 + 3 = 5$.
- Now, calculate the cube of this sum: $5^3 = 5 \times 5 \times 5 = 125$. This matches the second number in the first pair.
Applying the Pattern
- Consider the second pair, starting with the number 31.
- The sum of its digits is $3 + 1 = 4$.
- Apply the same operation (cubing the sum of digits): $4^3 = 4 \times 4 \times 4 = 64$.
Conclusion
Therefore, the missing number in the analogy 31 : ? is 64.
