How it is scored
Number series items are scored on accuracy with harder sequences weighted by difficulty, then standardized to compare you with same-age peers. They are a common marker of fluid reasoning and often feed into the quantitative section of an IQ test.
π‘ Tip: Always check the differences between consecutive numbers first, then the ratios, and look for two interleaved patterns if a single rule doesn't fit.
