What comes next in the following series?
A1, B1, C2, D3, E5, F8, ?
Show answer & explanation
Correct answer: D
Explanation
Given Series: A1, B1, C2, D3, E5, F8, ?
Analyze the letter pattern:
The letters are: A, B, C, D, E, F, ?
These are consecutive letters of the alphabet.
So, the next letter after F is G.
Analyze the number pattern:
The numbers are: 1, 1, 2, 3, 5, 8, ?
This is the Fibonacci sequence, where each term is the sum of the previous two:
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13
So, the next term is G13.
Hence, the correct answer is option (4).
