Answer:

Step-by-step explanation:
So generally a geometric sequence can be defined as:
which is the explicit form. The r, is what each previous term is being multiplied by to get the next value which is evident in the recursive form:
. Knowing this we can take two values which are "next" to each other to find what r is. In this case I'll just is 1 and 1/4, given these two values we know that:
, 1*r is just r... so what each term is being multiplied by is 1/4. So let's plug the values into the explicit formula:
(I didn't put an a_1 value in front, since it's just 1... so it's a bit redundant). Anyways using this formula we simply plug in 5 as n into the equation to find the 5th term: 
Answer: -3
Step-by-step explanation: m= -5-7/2+2=-12/4=-3
M=-3
Answer:

Step-by-step explanation:
A ball has a radius of 18 cm.What is the approximate volume of the ball?Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.
Answer:
T = 9
Step-by-step explanation:
SAMDEB
1. Subtract 7 from both sides. 6T + 7 - 7 = 61 - 7
2. 6T = 54
3. Divide both sides by 6, to isolate T. 6T ÷ 6 = 54 ÷ 6
4. Therefore, T = 9
X = 10
to find x -
7x = 8x - 10
180 - 70 = 110
110 = 6y + 20
y = 15
