Answer:
Step-by-step explanation:
Given:
The given sequence is 3, 5, 7, 9
The difference between the second and first term is 5 - 3 = 2
The difference between the third and second term is 7 - 5 = 2
The difference between the fourth and third term is 9 - 7 = 2
So, there is a common difference of 2. Thus a sequence which has the same difference is known as an arithmetic sequence.
The explicit formula to determine the term of an arithmetic sequence is given as:
Where,
Plug in 3 for and 2 for
. This gives,
Therefore, the explicit formula to represent the given sequence is:
