Sequence Pattern Analysis

The question presents a sequence of letters: B, C, E, G.

To find the next letter, we need to identify the pattern governing the sequence.

Letter to Number Mapping

  • Convert each letter to its corresponding position in the English alphabet:
    • B is the 2nd letter.
    • C is the 3rd letter.
    • E is the 5th letter.
    • G is the 7th letter.

Identifying the Numerical Pattern

The sequence of numbers is 2, 3, 5, 7.

This sequence represents the first five prime numbers:

  • $p_1 = 2$
  • $p_2 = 3$
  • $p_3 = 5$
  • $p_4 = 7$

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Determining the Next Term

The next prime number in the sequence after 7 is 11 ($p_5 = 11$).

We need to find the letter that corresponds to the 11th position in the alphabet.

Mapping Back to Letter

The 11th letter of the English alphabet is K.

Therefore, the next letter in the sequence is K.
