Number Analogy Pattern Identification

This question requires identifying a logical or arithmetic relationship between two pairs of numbers. We are given the first pair 23145 : 45367 and need to find the missing number related to 41235 using the same pattern.

Analyzing 23145 to 45367 Pattern

Let's examine the relationship between each digit of the first number (23145) and the corresponding digit of the second number (45367):

  • 2 becomes 4 (Difference: $4 - 2 = +2$)
  • 3 becomes 5 (Difference: $5 - 3 = +2$)
  • 1 becomes 3 (Difference: $3 - 1 = +2$)
  • 4 becomes 6 (Difference: $6 - 4 = +2$)
  • 5 becomes 7 (Difference: $7 - 5 = +2$)

The pattern observed is that each digit in the first number is incremented by 2 to get the corresponding digit in the second number.

Applying Pattern to 41235

We apply this same rule (add 2 to each digit) to the second pair, starting with the number 41235:

  • First digit: $4 + 2 = 6$
  • Second digit: $1 + 2 = 3$
  • Third digit: $2 + 2 = 4$
  • Fourth digit: $3 + 2 = 5$
  • Fifth digit: $5 + 2 = 7$

Combining these results, we obtain the number 63457.

Finding the Missing Number 63457

The number 63457 completes the analogy based on the identified pattern. This matches Option 1.
