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.
Here, we want to select which of the fractions are rational
To get this, we need to understand what rational numbers are
Rational numbers are numbers that can be expresed in form a/b where the value of b is not equal to zero
From the options in the question, we can see that all these numbers are directly expressed as fractions in the form a/b with none of the denominators being eual to zero
This means all the given fractions are rational
Answer:
The 25% discount on AED 4000 will be: 1000 AED
Step-by-step explanation:
Given
In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.
i.e
Discount amount = 25% of 4000
= 25/100 × 4000
= 0.25 × 4000
= 1000 AED
Thus, the 25% discount on AED 4000 will be: 1000 AED
