FEAST I style, test 2 of 15
Number series
Which number comes next? Find the pattern in the series before time runs out.
- Each series follows one rule: a fixed step, multiplying by a number, a growing step, two rules taking turns, two series woven together, or the sum of the two previous numbers.
- 15 series, 18 seconds each. Answer with the mouse or the keys 1–4.
- The wrong options are common mistakes, such as using the wrong step or missing that the step grows.
