In an odd-one-out question, three numbers follow the same rule and one breaks it. Here all four numbers are odd (or all even), so you have to think harder: which times table do three of them belong to?
✓ You passed this topic’s test.
Find the shared rule — “look for a table that three of the numbers belong to”
Use it for: Odd-one-out, classification and “which does not belong” questions.
Check: 7 × 6 = 42 and 7 × 7 = 49, so 45 falls between them and is not in the table of 7 ✓
Work it out in your head or on paper, type the answer and press Check. Stuck? Press “Show me how”.
