Filter out symbols first and count backwards from the rightmost remaining character.
Remove symbols
Original series: & % 4 6 @ 8 & 3 Ω 2 7 ʊ 9 # 1 * £ 1 + & @ 5. \text{Removing} symbols (&, \%, @,, &, Ω, ʊ, #, *, £, +, &, @) leaves only numbers: 4, 6, 8, 3, 2, 7, 9, 1, 1, 5.
Count from the right
The sequence of numbers is 4, 6, 8, 3, 2, 7, 9, 1, 1, 5. Counting from the right: 1st is 5, 2nd is 1, 3rd is 1, 4th is 9, 5th is 7, 6th is 2.
A: Represents the 5th number from the right, not 6th. B: Represents the 4th number from the right, not 6th. C: Represents the 3rd number from the right, not 6th.
D is correct because after dropping all symbols, the remaining sequence is 4, 6, 8, 3, 2, 7, 9, 1, 1, 5, and the 6th number from the right is 2.
In alphanumeric series questions, always perform the filtration step physically on paper to avoid accidental inclusion of symbols or skips.
