What is the explicit formula for this geometric sequence?

Mathematics
1 answer:
Kamila [148]3 years ago
5 0

Answer:

<h2>(-6)×3ⁿ⁻¹</h2>

Step-by-step explanation:

We notice that in this sequence (an) we multiply by 3 each time to get the next term

e.g :  (-6)×3 = -18

then

the commonn ratio q = 3

the first term a1 = -6

the explicit formula :

an = a1×qⁿ⁻¹ = (-6)×3ⁿ⁻¹

Is this sequence arithmetic,<br> geometric<br> or neither?<br> 3.5. -4, -7.5...
kvasek [131]

Answer:

Neither

Step-by-step explanation:

If the sequence was geometric, each term would be multiplied by the same multiplier to get to the next one. We can check if the multiplier is the same by taking a term and dividing it by the term before it. For example,

-4/3.5=-1.14285714

-7.5/-4=1.87500

The multiplier between the terms aren't the same so it's not geometric.

For arithmetic, the distances between each term would be the same, and we can take the same idea from the geometric sequence, but use subtraction instead of division

-4-3,5=-7.5

-7.5-(-4)=-3.5

Again, the distances aren't the same, so it's not arithmetic.

Which statement is true about f(x) = –6|x + 5| – 2?
snow_lady [41]

Answer:

Step-by-step explanation:

"The graph of f(x) is a horizontal compression of the graph of the parent function" is true; the graph will appear to be narrower than that of y = |x|.  I would prefer to state "the graph of f(x) exhibits vertical stretching of the original (parent) function graph."
