I've got confused, not sure if I give a classification of the formula that I worked out by solving the recurrence system or of the recurrence system.

I think it is the formula T(n) = 5 + 5n. In which case I *think* it's a no brainer because the only term is 5n and so,

T(n) = 5n is (O^2) and also it is O(n). Thus T(n) = 5n is of order n. Which means 5n is BIG THETA O(n).

Would appreciate ir if someone could verify I'm on the right track with this.
