---
"like terms" are terms that have the same variable content.
----
7x and 3x are "like terms"
---
7x and 3x^2 are not "like terms"
---
7abc and 3abc are "like terms"
----
7a^2bc and 3a^3bc are not "like terms".
=======================
Your Problem:
7m^2+6.5n-4n +2.5m-n
---
6.5n;-4n;-n; are all "like terms" and add up to 1.5n
---
7m^2 ; 2.5m ; are not "like terms" so cannot be combined.
---
Answer to your problem: 7m^2 + 2.5m + 1.5n
