Find the first 4 terms of the sequence defined by a(n) = a(n-1) + -3/n, a(0) = -3.

This is a similar equation like the one I sent you earlier. Thanks for your help.

Is there an easier way, I remember doing these types of equations earlier and I kinda had a hard time with them then. I'm just trying to get prepared for the test. Thanks Billy
a(n) = a(n-1) - 3/n means that
a(1) = a(0) - 3/1
a(2) = a(1) - 3/2
a(3) = a(2) - 3/3
etc.
a(1) = a(0) - 3/1 = -3 - 3/1 = -3 - 3 = -6. So a(1) = -6.
a(2) = a(1) - 3/2 = -6 - 3/2 = -7/2. So a(2) = -7/2.
a(3) = a(2) - 3/3 = -7/2 - 3/3 = -9/2. SO a(3) = -9/2
etc..
Let me know if this, along with my response to your preceding question, don't clarify the notation and its application.
