## What are the next 2 terms in the sequence 729 243 81 27?

The answer is 9; the next number is one-third of the number itself. 729÷3=243÷3=81÷3=27÷3=9.

**What is the common ratio in the geometric sequence 243 81 27 9?**

Calculus Examples This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 13 gives the next term. In other words, an=a1⋅rn−1 a n = a 1 ⋅ r n – 1 . This is the form of a geometric sequence.

### Which pattern will reach 729 first?

Finally, you can extend the pattern to find the seventh number. Keep multiplying by 3 until you reach the seventh number in the sequence. The first seven numbers in the sequence are 1, 3, 9, 27, 81, 243, 729. The answer is that the seventh number in the sequence is 729.

**What is the geometric mean between 4 and 16?**

Now the product of 4 and 16 is 64. The geometric mean is given by the root of the product of the two numbers. So the geometric mean of 4 and 16 will be the root of 64. Thus 8 is the geometric mean of 4 and 16.

#### How do you find two geometric mean?

Geometric Mean: If we want to take the geometric mean of two numbers, we just simply need to multiply the two numbers and get the square root of two numbers.

**What is the pattern rule for 243 81 27?**

Given the sequence of numbers 243, 81, 27, 9, it is apparent that each subsequent number is 1/3 of the number before it, e.g. 1/3 of 27 is 9 and 1/3 of 9 is 3. Therefore the next two numbers in the sequence are: 9/3 = 3, and 3/3= 1, i.e. the next two numbers in the sequence 243, 81, 27, 9, are 3, and 1.

## What is the ratio of 81 to 243?

Therefore, 81/243 simplified to lowest terms is 1/3.

**Which of the following is the formula for finding any term of a geometric sequence?**

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 .
