A₆ =12
a₇ = ?? = x
a₈ 27
In this case x is the geometric mean & as per the formula
geometric mean of 2 numbers =√(a₆ * a₈) = √(12*27)
& x=18.
Proof:
Find the common ratio between a₇ & a₆ ==> = ( x) / 12
now find the common ration between a₈ & a₇ ===> =27 / (x)
x/12 = 27/x ===> x² = 12*27 ==> x² = 324 & x =√324 = 18

Answer:
$131422
Step-by-step explanation:
Given :
Amount owed = $124,850
Commison on sale = 5%
Let :
Sale price of bulldozer = x
Sale price = amount owed + 5% of sale price
x = 124850 + 0.05*x
x = 124850 + 0.05x
x - 0.05x = 124850
0.95x = 124850
x = 124850 / 0.95
x = 131421.05263
To the nearest dollar = $131422
