Answer:
18
Step-by-step explanation:
<em>First, use the equation for geometric mean; an=a1r^n-1</em>
*where is an is the number at an n term, r is the ratio and a1 is the first number of the sequence.*
12 = a1 r^5
27 = a1r^7
From the equations above,
a1 = 128/81
r = 3/2
Therefore, the 7th term is:
an = (128/81) (3/2)^6
an = 18
hope this helps :)

Y=9x all you have to do is add 5 add 4x which will get you y=9x
Answer:
Step-by-step explanation:
3x + 2y + 2x + y = ......y is the same as 1y...combine like terms
5x + 3y <===
Answer:
the number is -6 (assuming "3 lots of" means 3 times)
Step-by-step explanation:
Let the number be x
1 less than a doubled number
2x-1
5 more than 3 lots of (times???) the number
3x+5
Solve for x
2x-1 = 3x + 5
-x = 5+1
x = -6
