Multiply, then add
Each term is the previous one ×2, then +6.
The next number is 314.
- 4 × 2 + 6 = 14
- 14 × 2 + 6 = 34
- 34 × 2 + 6 = 74
- 74 × 2 + 6 = 154
- 154 × 2 + 6 = 314

Number Series
Every pattern has a story.
Start with the gaps. Then look for a repeated operation, a familiar family of numbers, or two patterns taking turns.
Try a different lens
Look for multiplication, squares or cubes. If one rule doesn’t fit, inspect every other number.
Check the whole sequence
A useful pattern explains every shown number, not just the final pair. Then apply it once more.
