Prerequisites
How to Solve Prime Position Problems
Step 1: Recognize that letters correspond to prime number positions
Step 2: List prime numbers within 1-26: 2,3,5,7,11,13,17,19,23
Step 3: Convert each prime position to its letter
Step 4: Apply the pattern to find the next letter
Step 5: For primes beyond 26, wrap-around may be needed
Step 6: Verify the pattern for all given terms
Example Problem
Example: Find the next letter: B, C, E, G, K, ___ Solution: Step 1: Positions: B=2(prime), C=3(prime), E=5(prime), G=7(prime), K=11(prime) Step 2: Next prime after 11 is 13 Step 3: Position 13 = M Answer: M
