Quantitative Reasoning
Quantitative Reasoning on InView tests numerical patterns and relationships rather than routine calculation. Items may ask for the next term in a number series, a missing value in a proportional relationship, or the result of a multi-step word problem. The section rewards finding structure before computing.
Look at differences and ratios
For a series, first check constant differences, then check ratios, then check second differences. Also test alternating operations and familiar patterns such as squares, primes, and doubling plus a constant. Write the rule as an equation so you can test it on every term.
Work backward from the choices
When a rule is unclear, substitute a candidate answer and see whether it preserves the pattern across all terms. For word problems, translate the comparison into an equation before calculating; this prevents solving for the wrong quantity.
Worked example
Find the next term: 3, 7, 15, 31, ___. The differences are 4, 8, and 16-doubling-so the next difference is 32 and the term is 63. The same series also fits “double and add 1”: 3 × 2 + 1 = 7, 7 × 2 + 1 = 15, 15 × 2 + 1 = 31, so 31 × 2 + 1 = 63. Both checks agree.
Traps that cost marks
Assuming a constant difference after seeing only two gaps is a classic error. Mixing units, solving for the wrong quantity, and stopping at the first plausible rule without checking every term also lose marks. On comparison-style items, calculate both quantities rather than judging by appearance.
