Here's a step-by-step explanation:

In this series, each letter is obtained by multiplying the numerical position of the previous letter by a consecutive prime number, starting from 2.

Let's break it down:

• B is the 2nd letter of the alphabet. Multiplying 2 (prime) by the position of B (2) gives us 4.

• D is the 4th letter of the alphabet. Multiplying 3 (next prime after 2) by the position of D (4) gives us 12.

• H is the 8th letter of the alphabet. Multiplying 5 (next prime after 3) by the position of H (8) gives us 40.

• P is the 16th letter of the alphabet. Multiplying 7 (next prime after 5) by the position of P (16) gives us 112.

• X is the 24th letter of the alphabet. Multiplying 11 (next prime after 7) by the position of X (24) gives us 264.

Now, to find the next letter:

• We observe that the next prime number after 11 is 13.

• Multiplying 13 by the position of X (24) gives us 312.

• The 312th letter of the alphabet is Z.

Therefore, the next letter in the series is Z.
