Identify the odd one out:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 751
In three of the numbers the first digit is the sum of the other two:
Option (1) 751 — \(5+1=6\), not 7, so 751 is the odd one out
Option (2) 734 — \(3+4=7\), the first digit
Option (3) 853 — \(5+3=8\), the first digit
Option (4) 981 — \(8+1=9\), the first digit
