Write in Code

Code questions use a consistent mapping or transformation that must be inferred from examples.
Let’s learn
Core knowledge: Code questions use a consistent mapping or transformation that must be inferred from examples.
Infer a code rule, apply it consistently and verify with the example.
See it
If each letter shifts forward by 2, CAT becomes ECV: C→E, A→C, T→V (wrapping after Z when needed).
Try it together
Test candidate rules against every letter in two supplied example pairs.
Now you try
1. With +1 code, encode DOG. 2. Decode UJNF using −1. 3. If A=1, B=2, find the total for BAD.
Check your answers
1. EPH. 2. TIME. 3. 2 + 1 + 4 = 7.
