Numerical: number pattern MCQ - Practice Questions with Answers

The pattern is: bottom number = left number multiplied by one less than the right number. In the first set, 7 x (6 - 1) gives 35. In the second set, 12 x (5 - 1) gives 48. For the third set, 9 x (? - 1) must give 63, so ? - 1 = 7 and the missing number is 8. The numbers 13, 11, and 19 do not satisfy this same relation with 9 and 63.

In the consistent pairs, the second number is obtained by multiplying the first number by the next odd number. Thus 11 is multiplied by 13 to give 143, 5 is multiplied by 7 to give 35, and 13 is multiplied by 15 to give 195. For 7, the same pattern would require 7 multiplied by 9, giving 63. The printed pair gives 67 instead, so it does not follow the common rule. Therefore, the pair (7, 67) is the odd one out.
