What will come in place of question mark (?) in the following series? P3C,…

Explanation:

• First letters: P, R, T, V increase by 2 positions in the alphabet each time (P → R → T → V → X).

• Numbers: 3, 5, 8, 12 increase by successive increments of 2, 3, 4. The next increment is 5, so 12 + 5 = 17.

• Last letters: C, F, I, L increase by 3 positions each time (C → F → I → L → O).

Combining these gives the next term: X17O.
