G13
Letters move one step forward each time, and the numbers form the Fibonacci series (each number is the sum of the two before it).
Letters: A, B, C, D, E, F, G
Numbers: 1, 1, 2 (= 1 + 1), 3 (= 1 + 2), 5 (= 2 + 3), 8 (= 3 + 5), next = 5 + 8 = 13
Next term = G13
Check: the letter after F is G, so the H-terms are ruled out, and G9 does not follow the sum rule.
Hence, G13.
