To solve the problem of determining how 'PROMOTION' is encoded as 'QSP89' in the given code language, we need to understand the logic used for conversion. Let's analyze:
| Letter | Next Letter in Sequence |
|---|---|
| P | Q |
| R | S |
To write 'DEMOTION' similarly:
| Letter | Next Letter |
|---|---|
| D | E |
| E | F |
| M | N |
| O | P |
Follow this logic:
The encoded representation of 'DEMOTION' becomes 'EF89'. Thus, the answer is:
EF89
