Pearson lists Numeric Inference at OLSAT 8 Levels D–G. The general skill is to infer a rule from given number relationships and apply it consistently. Exact official items are secure, so the example here is independently written.
Original learning example
If 3 → 7 and 5 → 11, what would 8 → ? be under the same rule? Choices: 15, 16, 17, 18. Answer: 17. The rule doubles the starting number and adds one: 3×2+1=7, 5×2+1=11, and 8×2+1=17.
Check the rule
More than one operation can fit a single pair. A defensible answer must fit every provided pair. Write the rule in words before applying it to the unknown value, and verify that the result appears among the choices.
