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 greater then or equal to 1
f(1)=8, f(n=1)=f(n) - 5; for n greater then or equal to 1
f(1)=8, f(n=1)=f(n) + 5; for n greater then or equal to 1
f(1)=8, f(n=1)=f(n) - 3; for n greater then or equal to 1

Answer 1

The last one is correct, because each term is - 3 of the last term.

Answer 2

well each term is three less than the one before, so ...

Answer 3

So...

Answer 4

The last one is right...

Answer 5

Are you sure

Answer 6

Yes, definitely. The pattern goes down by 3 every time, and the last one is the only one that does that.

Answer 7

Just see for yourself:
8,5
What's happening there? your taking 8 then subtracting 3 to get 5.
Next sequence:
5,2
Same thing, taking 5 and subtracting 3 to get 2.
I know it's D because only D mentions going down by 3 each time.

Answer 8

Ok thanks but could u help me with this one too

Answer 9

Sure, and no problem.
