tween a float between 2 values

i have this healthbar th references a float value and for example lets think that float health equals 200 and and then it needs to equal 150 i dont want it to change instantly or change smoothly by time t.I want it to start reducing fast and as near it gets slow reduction speed.is itween capable of that?

 

Mathf.Lerp() can do that no problem.
