Find the first four terms of the sequence represented by the expression.

3n + 5 (1 point)
5, 8, 11, 14
8, 11, 14, 17***
3, 6, 9, 12
0, 8, 11, 14

• one more.....!!??? -

8. Use the function rule .
f(x) = 3x - 2.
Find the output .
f(1.5)
(1 point)

2.5
–2.5
6.5
–6.5

ummm.....no clue!

• so sorry, this is the last one! -

1.6, 0.8, 0.4, 0.2, . . .
(2 points)

is this an ok response?:

The sequence is geometric because it is being divided instead of adding/subtracting.

3n+5 is ok
#8. No clue? really?
For any x, f(x) = 3x-2
So, when f(1.5), wherever you see an x, plug in 1.5:
f(1.5) = 3(1.5)-2 = 4.5-2 = 2.5

No. The sequence is geometric because there is a constant ration between terms. Multiplication and division are really the same thing. In this case, the common ratio is 0.5 each term is 1/2 the term before.

Recall that geometric sequences are
a, ar, ar^2, ar^3, ...

It just happens that in this case r = 1/2

should i really put down what you said? im just saying, cuz dad said my answer was fine...
