Alphanumeric Series Pattern Analysis
The given series is an alphanumeric sequence: Q, 18, S, 16, U, 13, W, ?
This series alternates between letters and numbers. We need to identify the pattern for both.
Letter Sequence Progression
Let's examine the letters:
- Q is the 17th letter of the alphabet.
- S is the 19th letter. (Q + 2 positions)
- U is the 21st letter. (S + 2 positions)
- W is the 23rd letter. (U + 2 positions)
The pattern for letters is consistent: add 2 to the position of the previous letter (skip one letter in between).
Number Sequence Progression
Now let's examine the numbers:
- The first number is 18.
- The second number is 16. (18 - 2)
- The third number is 13. (16 - 3)
The pattern for numbers involves subtracting an increasing sequence. The subtractions are -2, -3. The next logical subtraction in this sequence would be -4.
Calculating the Missing Number
Following the number pattern, the next step is to subtract 4 from the last number (13).
Calculation: $13 - 4 = 9$
Therefore, the number that replaces the '?' is 9.
