Identify the number that does NOT relate to the following series.
25, 28, 23, 30, 21, 33
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 33
Given series: 25, 28, 23, 30, 21, 33
Here, 2 is subtracted alternately and 2 is added alternately.
25 - 2 = 23; 23 - 2 = 21
28 + 2 = 30; 30 + 2 = 32
Hence 33 is odd.
