Question

Find the missing term in the following alpha-numeric series : 
C-24, H-19, M-14, ?, W-4

The correct answer is
R-9

To find the missing term in the given alpha-numeric series, we first analyze the series provided:

  • C-24
  • H-19
  • M-14
  • ?
  • W-4

We need to identify the pattern both in the alphabetical and numerical parts to find the missing term.

Step 1: Identify the pattern in the alphabetical part:

  • The alphabetical sequence is C, H, M, ?, W.
  • Analyzing the pattern in the letters, we find:
    • C is the 3rd letter in the alphabet.
    • H is the 8th letter, which is 3 + 5 = 8.
    • M is the 13th letter, which is 8 + 5 = 13.
    • The next letter should be M + 5 = 18, which corresponds to the letter R (since R is the 18th letter in the alphabet).
    • W is the 23rd letter, which is 18 + 5 = 23.
  • Thus, the alphabetical pattern increases by 5. The missing letter is R.

Step 2: Identify the pattern in the numerical part:

  • The numerical sequence is 24, 19, 14, ?, 4.
  • The number reduces by 5 each time:
    • 24 - 5 = 19
    • 19 - 5 = 14
    • 14 - 5 = 9
    • 9 - 5 = 4
  • Thus, the missing number is 9.

Putting these patterns together, the missing term in the series is R-9.

Conclusion: The missing term is R-9, which matches the option R-9.
