HELP BECAUSE IM STUPID!
mixer [17]
I don't think you're stupid. ^^
Let's take the third term, 8. If n=3, then an should be 8.
The first answer gives 15+2.5*3=22.5.
The second answer gives 15.5+2.5=23.
The third answer gives 15-2.5*3=7.5.
The fourth answer gives 15.5-2.5*3=8.
Choice 4 is correct.

Let's try to actually find the equation on our own.
The equation for an arithmetic series is an=a0+dn where a0 is the term that comes before the first term.
The first term given is 13 and it decreases by 2.5 each time so n=-2.5 and the term that would be before 13 is 15.5.
Thus the equation is an=15.5-2.5n

Find the coordinates of the midpoint of the segment whose endpoints are h(6,4) and k(2,8)
ozzi

Answer:

(4,6)

Step-by-step explanation:

we know that

The formula to calculate the coordinates of the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have that

The coordinates of hk

h(6,4), k(2,8)

substitute in the formula to calculate the midpoint

M(\frac{6+2}{2},\frac{4+8}{2})

M(\frac{8}{2},\frac{12}{2})

M(4,6)
