In a certain code language, "CAB" is written as "12" and "LAN" is written as "54". How will "WAN" be written in that same code language?

Let's determine the pattern using the standard English alphabetical positions ($A=1,B=2,C=3,\dots ,Z=26$):
1. Check "CAB":

* Positional values: $C=3$, $A=1$, $B=2$
* Sum of values = $3+1+2=6$
* Coded representation = $6\times 2=12$

2. Check "LAN":

* Positional values: $L=12$, $A=1$, $N=14$
* Sum of values = $12+1+14=27$
* Coded representation = $27\times 2=54$

The rule is: $\text{Code}=(\text{Sum of positional values})\times 2$.

3. Apply the rule to "WAN":

* Positional values: $W=23$, $A=1$, $N=14$
* Sum of values = $23+1+14=38$
* Coded representation = $38\times 2=76$
