Number Series Test
Find the pattern and enter the next number in each series. The sequences follow mathematical rules — either polynomial patterns (where differences between terms are predictable) or compositional rules (where each number depends on previous numbers in the series).
Almost done!
Two optional questions, asked once: your age and sex let the results be broken down by who took the test.
Sex as at birth; gender as you identify. Languages you grew up speaking; several are fine, separated by commas. Leave blank anything you would rather not say.
