Select the option that will fill in the blank and complete the given letter series.
A, B, D, G, K, P, _______

Correct option is C

given letter series:
A, B, D, G, K, P, _______
The first letter is A (1st letter of the alphabet).
The second letter is B (2nd letter of the alphabet).
The third letter is D (4th letter of the alphabet).
The fourth letter is G (7th letter of the alphabet).
The fifth letter is K (11th letter of the alphabet).
The sixth letter is P (16th letter of the alphabet).
The pattern here shows increasing gaps between the letters:
A (1), B (2): +1
B (2), D (4): +2
D (4), G (7): +3
G (7), K (11): +4
K (11), P (16): +5
Following this pattern, the next letter should be:
P (16) + 6 = 22nd letter of the alphabet, which is V.
So, the next letter in the series is V.
The correct answer is (c) V.
