Indeed, this is a geometric sequence.
The common ratio is 4.
(To find this answer, divide a number in the term to the number previous to that particular term. for example, 12 and 3. Divide 12 and 3, and it will give you 4.)
Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
- Segment AB: 10 cm
- Midpoint of AB: 10/2 = 5 cm
Next let's find the midpoint of BC.
- Segment BC: 5.2 cm
- Midpoint of BC: 5.2/2 = 2.6 cm
In order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
Therefore, the difference between the midpoints of AB and BC is 2.4 cm.
A real world example of this equation might look something like this:
John Smith wanted to subscribe to Vague Co. In order to subscribe, there is an initial fee of $60, and an additional fee of $25 for each month that he's subscribed. However, John found another company he wanted to subscribe to, Random Inc., which had an initial fee of $20 and an additional fee of $35 per month. After doing a bit of math, John found that the cost to subscribe to both companies is equal for x months. How many months would it take for the costs of both subscriptions to be equal?
60 + 25x = 35x + 20 Given
60 = 10x + 20 Subtract 25x from both sides
40 = 10x Subtract 20 from both sides
4 = x Divide both sides by 10
It would take 4 months for the costs of a subscription to Vague Co. and Random Inc. to be equal.
