MediumOriginal questionWhat is the next letter in the series A, B, D, H, ?
Show the answer and explanation
CorrectNot quiteAnswer D
Correct answer: D
Explanation
Positions: A = 1, B = 2, D = 4, H = 8.
Each position doubles (the jumps are 1, 2, 4), so the next position is 16, which is P.
Worth noting
L (12) adds 4 again, and N (14) adds 6, treating the jumps as rising by 2. The jumps 1, 2, 4 double, so the next jump is 8.
