Model X was launched before Model Z. Four models were launched between Model X and Model Z.
Case 1:
| MODEL | YEAR OF LAUNCH |
| X | 2013 |
| | 2014 |
| | 2015 |
| | 2016 |
| | 2017 |
| Z | 2018 |
| | 2019 |
Case 2:
| MODEL | YEAR OF LAUNCH |
| | 2013 |
| X | 2014 |
| | 2015 |
| | 2016 |
| | 2017 |
| | 2018 |
| Z | 2019 |
Two models were launched between Y and Z. Model V was launched in an even year before model Y.
So case 2 is invalid.
Case 1:
| MODEL | YEAR OF LAUNCH |
| X | 2013 |
| V | 2014 |
| Y | 2015 |
| | 2016 |
| | 2017 |
| Z | 2018 |
| | 2019 |
Model T was launched immediately before Model N. Model P was launched after model X.
| X | 2013 |
| V | 2014 |
| Y | 2015 |
| T | 2016 |
| N | 2017 |
| Z | 2018 |
