Can someone ? i’m completely blanking

The pattern is adding 2 stars on top of the previous figure, so figure number 4 would look like this:

* *

* *

* *

* *

Since the pattern is adding 2 stars every time, the explicit formula (for the number of stars) would be

Since when n=1, i.e. figure 1, we have 2*1=2 stars

when n=2, i.e. figure 2, we have 2*2=4 stars

when n=3, i.e. figure 3, we have 2*3=6 stars

and so on.

The recursive formula lays on the fact that we add 2 stars to the previous figure, which means that the fomula is

In fact, what we just wrote is simply "the number of stars at a given iteration is the number of stars at the previous iteration, plus 2.

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
