Question

Find the first four values of the sequence defined recursively by
a(0)=2, a(n+1)=a(n)-4

Answer 1

@nechamoosh Give it a try.

Answer 2

well im not sure if a(0) counts as one but thats given..
then i just get stuck cuz it says a(n+1)=a(n)-4. but when i plug in a number they are not equal like n=1 for example then i get 2 and -3

Answer 3

a(0) counts.

Answer 4

What do you mean by 2 and -3?
