Answer:
Option B
Explanation:
First check the alphabetical order, but we can't find anything there.
Then try GAPS,
A 4 F 1 H
A 6 H 3 L
A 8 J 2 M
A 16 R 4 W
A 12 N 3 R
But no clue.
Try adding the numbers we got in gaps,
4+1 = 5
6+3 = 9
8+2 = 10
16+4 = 20
12+3 = 15
But no clue.
Subtract the numbers,
4-1 = 3
6-3 = 3
8-2 = 6
16-4 = 12
12-3 = 9
Again no clue.
Multiply the numbers
4 X 1 = 4
6 X 3 = 18
8 X 2 = 16
16 X 4 = 64
12 X 3 = 36
All numbers except 18 are square numbers. So option b is the Odd one.
