Answer: 1, 1&1/4, 3/2, 1&6/8
Step-by-step explanation:
Since the above sequence is a geometric sequence
For an nth term in a geometric sequence
That's
where
r is the common ratio
a is the first term
n is the number of terms
From the question
a = 4.05
r = 1.35 / 4.05 = 0.33
Substitute the values into the above formula
We have
Hope this helps you
The first thing to do is to substitute the b and c. The equation will look like this, a+3a+5a=180. Then you must add the a's all together because they are all the same, remember that "a" represents 1. It will look like this in plain 1 + 3 + 5. Then the equation is 9a = 180. to get the "a" you must eliminate or divide the equation into 9 and it will look like this, <u>9a</u> = <u>180</u> Then the answer will be a = 20

Answer:
97.5
Step-by-step explanation:
75,85,90,105,120,150
90 and 105 are the middle, and median means the middle, but you can only have one answer.
90+105=195
195÷2=97.5
97.5 is the middle of all these numbers
7/8 - 3/8 = 4/8 ( When Simplified it is 1/2)
Or
18/20 - 8/20 = 10/20 ( Also when Simplified it is 1/2)
