A series is given with one term missing. Choose the correct alternative from the given ones that will complete the series.TUW, ZAC, FGI, LMO, ?

Let's analyze the pattern by looking at the first letter of each group:T (20) $\to$ Z (26): $+6$ Z (26) $\to$ F (6): $+6$ F (6) $\to$ L (12): $+6$ L (12) $+6=18\to$ RNow let's check the relationship within each letter group:T(20) $+1=\text{U}(21)$, U(21) $+2=\text{W}(23)$ Z(26) $+1=\text{A}(1)$, A(1) $+2=\text{C}(3)$ F(6) $+1=\text{G}(7)$, G(7) $+2=\text{I}(9)$ L(12) $+1=\text{M}(13)$, M(13) $+2=\text{O}(15)$ Following this $+1,+2$ pattern for the next group starting with R (18):First letter: R (18)Second letter: $18+1=19\to$ SThird letter: $19+2=21\to$ UThus, the next term in the series is RSU.
