## What is the recursive formula for this geometric sequence?

Recursive formula for a geometric sequence is an=an−1×r , where r is the common ratio.

Which formula can be used to find the nth term of the geometric sequence below?

The nth term of a geometric sequence with first term a and the common ratio r is given by an=arn−1 a n = a r n − 1 .

What is the common ratio for the geometric sequence?

2
The common ratio is the number you multiply or divide by at each stage of the sequence. The common ratio is therefore 2. You can find out the next term in the sequence by multiplying the last term by 2.

### What is sequence equation?

An arithmetic sequence can be defined by an explicit formula in which an = d (n – 1) + c, where d is the common difference between consecutive terms, and c = a1.

What is the formula for geometric sequences?

The explicit formula for a geometric sequence is of the form an = a1r-1, where r is the common ratio. A geometric sequence can be defined recursively by the formulas a1 = c, an+1 = ran, where c is a constant and r is the common ratio.

How do you find the nth term in a sequence?

Solution: To find a specific term of an arithmetic sequence, we use the formula for finding the nth term. Step 1: The nth term of an arithmetic sequence is given by an = a + (n – 1)d. So, to find the nth term, substitute the given values a = 2 and d = 3 into the formula.

#### How do you find the 12th term of a geometric sequence?

⇒ common ratio =r=3 and the given sequence is geometric sequence. Where an is the nth term, a is the first term and n is the number of terms. ⇒ 12th term is 708588 . ⇒Sum=1062880 .

What is the 12th term of the geometric sequence?

⇒ common ratio =r=3 and the given sequence is geometric sequence. Where an is the nth term, a is the first term and n is the number of terms. ⇒ 12th term is 708588 .

How do you find the ratio of a sequence?

You can also think of the common ratio as a certain number that is multiplied to each number in the sequence. You can determine the common ratio by dividing each number in the sequence from the number preceding it. If the same number is not multiplied to each number in the series, then there is no common ratio.

## What are sequences in math?

In mathematics, a sequence. A sequence is an ordered list of numbers (or other elements like geometric objects), that often follow a specific pattern or function. Sequences can be both finite and infinite.

How do you find the first term of a sequence?

a is the first term, and ; d is the difference between the terms (called the “common difference”) And we can make the rule: x n = a + d(n-1) (We use “n-1” because d is not used in the 1st term). Geometric Sequences. In a Geometric Sequence each term is found by multiplying the previous term by a constant.

What is the pattern of the number sequence 4444 – 36 and 20-12?

44 – 36 = 8 and 20 – 12 = 8. The pattern of the sequence is, therefore, the addition of 8 to the preceding term. n = 20 + 8 = 28. What are the Types of Number Sequence? There are many number sequences, but the arithmetic sequence and geometric sequence are the most commonly used ones. Let’s see them one by one.

### What are the different types of number sequences?

There are many number sequences, but the arithmetic sequence and geometric sequence are the most commonly used ones. Let’s see them one by one. This is a type of number sequence where the next term is found by adding a constant value to its predecessor.

Why is it important to learn the sequence of numbers?

By learning and excising number sequence, an individual can sharpen their numerical reasoning capability, which helps our daily activities such as calculating taxes, loans, or doing business. For this case, it is important to learn and practice number sequence. Which list of numbers makes a sequence?
