Observe the pattern of each position in the series: 
1st letters: A, C, E, G, I, ? 
These increase by 2 in alphabetical order: A(1), C(3), E(5), G(7), I(9), so next is K(11). 
2nd letters: P, Q, R, S, T, ? 
These increase by 1: P(16), Q(17), R(18), S(19), T(20), next is U(21). 
3rd letters: Z, Y, X, W, V, ? 
These decrease by 1: Z(26), Y(25), X(24), W(23), V(22), next is U(21). 
4th letters: L, N, P, R, T, ? 
These increase by 2: L(12), N(14), P(16), R(18), T(20), next is V(22). 
5th letters: T, R, P, N, L, ? 
These decrease by 2: T(20), R(18), P(16), N(14), L(12), next is J(10). 
Thus the next term is \(\boxed{KUUVJ}\).
