Relating two number patterns
The question
Two rules, two patterns
row 1:6→18
row 2:12→36
row 3:18→54
row 4:24→72
row 1:6→18
row 2:12→36
row 3:18→54
row 4:24→72
row 1:6→18
row 2:12→36
row 3:18→54
row 4:24→72
- Two patterns side by side, and the question is the LINK between them — the one number that turns every left value into the one beside it.
- Read it off any complete row. Row 1: 6 on the left, 18 on the right — 18 ÷ 6 = 3.
- Check it holds down the column: 12 × 3 = 36, 18 × 3 = 54. Every bottom number is 3 times the top one, so the rule is × 3.
