Show answer & explanation
Correct answer: D
Check every numeral in the sequence to see if the element before it is a vowel (A, E, I, O, U) and the element after it is a consonant. The numerals satisfying this are: 5 at position (… A, 5, B …) → preceded by A (vowel) and followed by B (consonant)
6 at (… E, 6, D …) → E (vowel) before, D (consonant) after
6 at (… E, 6, P …) → E before, P after
7 at (… U, 7, T …) → U before, T after
Total = 4.
