Question

What is the fourth term in this sequence?

tn=3.2n-5 i dont get it...

Answer 1

\(t_{0} = 3.2(0) - 5 = -5\)
\(t_{1} = 3.2(1) - 5 = -1.8\)
\(t_{2} = 3.2(2) - 5 = 1.4\)
etc.

It is possible that you are to start with n = 1, rather than n = 0 as I demonstrated, above.

Answer 2

ok thanks:)

Answer 3

@tkhunny the answers are -7.2
-16.8
7.8
though

Answer 4

@Frostbite @AriPotta

Answer 5

Keep going:

\(t_{3} =3.2(3)−5=4.6\)
\(t_{4} =3.2(4)−5=7.8\)

And I think we're done.

Answer 6

you have to substitute 4 for n

Answer 7

oooooh thanks:)
