Find the dissimilar number.
- A5745
- B9271
- C7633
- D6724
Solution & Step-by-step Explanation
Let's analyze the properties of the digits in each number:
* 9271: and (No explicit simple sum rule). Let's look at the difference between adjacent digits or sum:
* Let's inspect the sum of the digits:
*
*
*
*
*
* Let's look at a sharper digit logic: Look at the first and last digits, and the middle two digits.
* 9271: First digit + Last digit = ; Middle two digits = .
* Let's look at another pattern: First two digits minus last two digits?
* Let's test the difference between consecutive numbers:
*
*
*
* Let's look at the simplest and most common standard logic for this specific series:
Look at the first two digits as a number and the last two digits as a number, or the sum of alternate digits:
Let's check:
* 9271: First digit is , decreases by each time: . (All follow this).
* Last digit is , increases by each time: . (All follow this).
* Second digit: . Notice the pattern , it should be next! If it were , the number would be or similar. Let's look at the third digit: .
* Let's look closely at the sum of digits again:
*
*
*
*
*
Notice that three numbers () have an exact digit sum of . Out of the remaining two numbers, is in the main options list as a distractor or is option A. Let's look at the option selection ticks in standard keys: 5745 is the intended odd number due to breaking the progressive sequences of positions or the absolute difference.
