Odd man out series - Quantitative Aptitude (MCQ) questions for Q. 112
Q. Determine the odd man out:
15, 16, 34, 105, 424, 2124- Published on 15 Jun 15a. 105
b. 424
c. 34
d. 2124
ANSWER: 2124
The following pattern has been followed in this question:
16 = 15 x 1 + 1
34 = 16 x 2 + 2
We have established that previous number is multiplied by increasing numbers (1,2,3,4.....) and then added by increasing numbers (1,2,3,4...)
105 = 34 x 3 + 3
424 = 105 x 4 + 4
2125 = 424 x 5 + 5
=> 2124 is incorrect
