If you look at clue #2 first then you see that if you know one of the numbers then the other number is 3 less than it, so if I let one of the numbers be x then the other is
x - 3. Now clue # 1 says the sum of the two numbers is 21 so
x + (x - 3) = 21
B.26.00 Because if you divide 127.90 by 5 you will 25.58 and you round that up to 26.00
Answer:
Given sequence is an arithmetic sequence.
Step-by-step explanation:
Given sequence is:
125, 25, 5, .. ..
Here

- A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.
- A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.
Finding the common ratio

As we can see that the common ratio is same, the given sequence is a geometric sequence.
