| Number pattern: find the step (difference) between consecutive terms. |
| Pattern | = | 2.07, 2.09, ?, ?, 2.15, 2.17 |
| Find the difference using known terms: 2.09 - 2.07 = 0.02, 2.17 - 2.15 = 0.02. The pattern adds 0.02 each step. | ||
| First missing | = | 2.09 + 0.02 = 2.11 |
| Second missing | = | 2.11 + 0.02 = 2.13 |
| Check: 2.13 + 0.02 = 2.15. Matches. | ||
