Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row: 17, 26, 60
Second row:8, 15, 31
Third row: 11, 19, ?
(NOTE: Operations should be performed on the whole numbers, without breaking down the number into its constituent digits. For example, 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 41
Given pattern:
| 17 | 26 | 60 |
| 8 | 15 | 31 |
| 11 | 19 | ? |
The logic used here is:
(17 x 2) - 8 = 26; (26 x 2) + 8 = 60
(8 x 2) - 1 = 15; (15 x 2) + 1 = 31
Similarly, (11 x 2) - 3 = 19; (19 x 2) + 3 = 41
Hence, option 2 is the correct option.
