Letter Number Series

The Letter Number Series refers to the series that arranges both numbers and letters in sequential order so that every term in that specific series is calculated with particular specific rules.

Letter-number series is the combinations of two series, letter series and number series. 

Example : Find the missing term?

J2Z, K4X,I7V, ......, H16R, M22P

Solution : 

This pattern consists combination of two series for first place and other two terms vary with two different series as :
For first place : J,I, H, G, ...... and K, L, M, N, .....
For second place : 2, 4, 7, 11, 16, 22, ......
and for third place : Z, X, V, T, R,P, ......
∴ Missing Term = L11T.
