Question 3

Fill in the missing term: W11, U9, S7, ?, O3
Letters move back by 2; numbers -2 each time.
series, reverse

Question 4

Find the next term: T1, Y6, D11, I16
Letters move by +5, number increments by 5. Wraparound used for letters.
series, modular

Question 5

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: L4, Q4, R8, W8, X12
Odd-indexed positions: letter advances by 3 from L, number = (position+2)×2 = 14 at position 5. Next term: A14.
