In the following question, select the number which can be placed at the sign of question mark (?) from the given alternative. 18 90 5 13 143 11 7 ? 5
35
The pattern across each row is: middle number = first × last + (first − last), i.e. the product plus the difference of the outer numbers.
Row 1: \(18 \times 5 + (18-5) = 90 + 13 \ne 90\). Try simpler: \(18 \times 5 = 90\). Row 2: \(13 \times 11 = 143\). Row 3: \(7 \times 5 = 35\).
The middle entry in each row equals the product of the outer two numbers. Hence the missing value is 35.
