Question

Would it be a geometric sequence?

anonymous · Answer

200+(w+4.2) where w is the number of weeks. I believe that is it but I can't say 100%

anonymous · Answer

Would I be putting it in this equation form; an = dn + c ?

anonymous · Answer

i dont know

anonymous · Answer

sorry

Don't even think about it in terms of the equation. Just from what the equation tells you, how tall would you expect the tree to be after one (1) week?

it should be multiplied;   f(w)=200 + 4.2w
