Find the missing term in the series: AZB, CYD, EXF, GWH, ?
The missing term is IVJ. The first letters move forward by two (A, C, E, G, I), the middle letters move backward by one (Z, Y, X, W, V), and the last letters move forward by two (B, D, F, H, J). Together they form IVJ.

Explanation
The first letters are A, C, E, G, so each rises by 2, giving I. The middle letters are Z, Y, X, W, going backwards, so the next is V. The last letters are B, D, F, H, rising by 2, so the next is J. The term is IVJ. IVH wrongly repeats the last letter H.
