Refer to the following letter series and answer the question that follows. Counting to be done from left to right only. (Left) D E I V D I J Y T Z A K F Z S M U I Y E Q (Right) How many such vowels are there, each of which is immediately preceded by a consonant and also immediately followed by a vowel?1

We are looking for the pattern: [Consonant] → [Vowel] → [Vowel] Vowels: A, E, I, O, U Consonants: All other letters (D, V, J, Y, T, Z, K, F, S, M, Q) Let's check the letter series step-by-step: D – E – I Preceded by consonant (D), Target vowel (E), Followed by vowel (I) M – U – I Preceded by consonant (M), Target vowel (U), Followed by vowel (I) There are two such vowels are there, each of which is immediately preceded by a consonant and also immediately followed by a vowel.
