Question

the first four terms of a sequence are shown below

8,5,2,-1

which of the following functions best defines this sequence?


f(1)=8,f(n+1)=f(n)+3;for n > 1
f(1)=8,f(n+1)=f(n)-5;for n > 1
f(1)=8,f(n+1)=f(n)+5;for n > 1
f(1)=8,f(n+1)=f(n)-3;for n> 1

the > are suppose to have a line under them

Answer 1

well do you see what the difference is or how to find it?

Answer 2

\[\huge\color{blue}{\huge {\bbox[5pt,cyan,border:2px solid purple]{a_{n}-a_{(n-1)}=difference}}}\]
