In the following letter series, how many letters of K are preceded by G but not followed by P? C L M G K P N M G K C L O G K L X G K B K G K A
4
To solve this letter series problem, we need to carefully examine the given sequence of letters and identify specific patterns. The question asks us to count how many times the letter 'K' appears under two specific conditions: first, it must be immediately preceded by the letter 'G', and second, it must NOT be immediately followed by the letter 'P'.
Letter Series Examination
The given letter series is:
C L M G K P N M G K C L O G K L X G K B K G K A
Conditions for Counting 'K'
We are looking for occurrences of 'K' that satisfy the following two conditions simultaneously:
- The letter immediately preceding 'K' must be 'G'. This means we are looking for the pattern "G K".
- The letter immediately following 'K' must NOT be 'P'. This means the pattern "G K P" should be excluded. We are looking for "G K X" where 'X' is any letter EXCEPT 'P'.
Step-by-Step Series Analysis
Let's go through the series letter by letter and identify each 'K', then check its surrounding letters against the given conditions:
| Segment of Series | Preceding Letter | Target Letter ('K') | Following Letter | Condition 1 (Preceded by 'G'?) | Condition 2 (Not followed by 'P'?) | Count? |
|---|---|---|---|---|---|---|
| C L M G K P N M G K C L O G K L X G K B K G K A | G | K | P | Yes | No (it is 'P') | No |
| C L M G K P N M G K C L O G K L X G K B K G K A | G | K | C | Yes | Yes (it is 'C', not 'P') | Yes (1) |
| C L M G K P N M G K C L O G K L X G K B K G K A | G | K | L | Yes | Yes (it is 'L', not 'P') | Yes (2) |
| C L M G K P N M G K C L O G K L X G K B K G K A | G | K | B | Yes | Yes (it is 'B', not 'P') | Yes (3) |
| C L M G K P N M G K C L O G K L X G K B K G K A | B | K | G | No (it is 'B') | N/A | No |
| C L M G K P N M G K C L O G K L X G K B K G K A | G | K | A | Yes | Yes (it is 'A', not 'P') | Yes (4) |
Counting the Occurrences
Based on our step-by-step analysis, we found the following instances where 'K' is preceded by 'G' but not followed by 'P':
- The 'K' in
G K C - The 'K' in
G K L - The 'K' in
G K B - The 'K' in
G K A
There are a total of 4 such occurrences in the given letter series.
