FAQs
The terms in the sequence are said to increase by a common difference, d. For example: 3, 5, 7, 9, 11, is an arithmetic progression where d = 2. The nth term of this sequence is 2n + 1 . In general, the nth term of an arithmetic progression, with first term a and common difference d, is: a + (n - 1)d .
What rule will correctly describe the sequence 3 5 7 9? ›
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 2 to the previous term in the sequence gives the next term.
Which statements describe the sequence 3, 5, 7, 9, 11? ›
Answer: The correct statements are, The 4th term of the sequence is 9, The domain of the sequence is all natural numbers, and (4,9) lies on the graph. Step-by-step explanation: Since, the given sequence, –3, 5, –7, 9, –11, ….. So, we can say that the above sequence has infinite number of terms.

Is 1/3,5/7,9 a geometric sequence? ›
Algebra Examples
This is an arithmetic sequence since there is a common difference between each term.
To find the nth term of a sequence use the formula an=a1+(n−1)d. Here's how to understand this nth term formula. To find the nth term, first calculate the common difference, d . Next multiply each term number of the sequence (n = 1, 2, 3, …) by the common difference.
What is the rule of 3 5 7 9 11 13 15? ›
Answer: 3, 5, 7, 9, 11, 13, 15 is an arithmetic progression. Here the common difference between two consecutive terms is 2. A sequence in which the difference between any two consecutive terms is a constant is called as arithmetic progression.
