Refer to the given letter-number-symbol string and answer the following question: D # M 5 $ 8 G ψ F 8 % U 3 Ø W 6 ÷ E & 4√ 9 Ω 7 A Four of the following five options are alike in a certain way based on their positions in the given string and so form a group. Which is the one that does not belong to that group?

Refer to the following number-symbol series and answer the question that follows. Counting is to be done from left to right only. (All numbers are single-digit numbers.) (Left) 3 6 @ 4 5 6 # 2 9 4 = 3 1 9 4 5 % 3 6 8 7 & 1 7 * 8 (Right) How many such symbols are there each of which is immediately preceded by an odd number and also immediately followed by an even number?
