What comes next in the following series? A1, B8, A27, B64, ?
A125
This is a mixed (alphanumeric) series, so we analyse the letters and the numbers separately.
The letters run A, B, A, B, ... alternating between A and B.
After the fourth term B, the alternation returns to A, so the next letter is A.
Now look at the numbers: \(1, 8, 27, 64, \ldots\)
These are perfect cubes: \(1=1^{3},\ 8=2^{3},\ 27=3^{3},\ 64=4^{3}\).
The next cube is \(5^{3}=125\).
Combining the next letter A with the next number 125 gives \(A125\).
Hence the term that comes next in the series is A125.
