Consider a geometric sequence

let

and the common ratio be r, then the sequence is constructed as follows:

we can observe that each term of the sequence is its previous term * r.
In the given sequence, to find the common ratio we divide 6,561 by −2,187 and get -3. This means that

Let the first term

,
then the eighth term is

Answer: -3
Answer:
25%
Step-by-step explanation:
Coin flip with tails: 1/2
1,2, or 3 on cube: 1/2
1/2*1/2 = 1/4
1/4 = 25%
Answer:
<em>m<ZXY - m<WXZ = m<WXY
</em>
Step-by-step explanation:
given:
point Z is in the interior of <WXY creating XZ.
<em>if m<WXZ = 20
</em>
<em> m<WXY = 100
</em>
find:
what would equation would you set up to find the missing angle measure?
solution:
Since Z is interior of <WXY
<em>m<ZXY - m<WXZ = m<WXY
</em>
<em><WXY = 100 - 20 = 80°
</em>
therefore, the equation would be <em>m<ZXY - m<WXZ = m<WXY </em>
F= G(m1m2/d^2)
First divide all terms by G
G(m1m2/d^2) / G = F/G
Cancel common Factor:
m1m2 / d^2 = F/G
Multipl;y both sides by d^2:
m1m2 = F/G * d^2
Divide both sides by m2:
m1 = F /G * d^2 /m2
Simplify:
m1 = Fd^2/Gm2
