Summary: The next three terms of the sequence 3, 9, 27, 81, . . . are243, 729 and 2187.

What is the sequence 3 9 27 81 243?

The next three terms of the sequence 3, 9, 27, 81, 243 are 729, 2187, and 6561.

What are the next three terms of 1/3,9,27?

Explanation. Find the common ratio (r) by dividing any term by its preceding term. r = 3/1 = 3. Use the common ratio to find the next 3 terms: 273 = 81, 813 = 243, 243*3 = 729.

GCSE Maths - How to Write Expressions for the nth term of Arithmetic Sequences (2026/27 exams)

What is the rule for this pattern: 1/3,9,27?

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 3 gives the next term.

Which sequence is an AP 1-3-9-27?

Since the Common Difference between the consecutive terms is not the same always, thus the sequence is not an A.P. Therefore, the series 1 , 3 , 9 , 27 , . . . . . . is not an A.P.

What is the geometric mean of 3 9 27 81243729 2187?

The geometric mean of 3,9,27,81,243,729,2187 is 81.

How do I find the next number in a sequence?

To find the next number in a sequence, you must first identify the pattern (e.g., adding a constant, multiplying, squares, cubes, or alternating operations) by examining the relationship between the given numbers; without the specific numbers in the sequence, the next number cannot be determined, but common methods involve finding differences, ratios, or recognizing powers. 

What is the next number in the sequence 3,6,9,12 ___?

The next number in the sequence 3, 6, 9, 12, __? is 15. This is because the sequence increases by 3 each time.

What is the next number in the pattern 27 9 3?

Sequence pattern of 27, 9, 3, 1, | Wyzant Ask An Expert.

What is the next number in the sequence 3 9 27 81 162 180 243 270?

Community Answer

The next number in the sequence 3, 9, 27, 81 is 243. This is a geometric sequence, each term is the product of the previous term and a constant, in this case, the constant is 3.

Which term of the sequence 1, 3, 9, 27 is 6561?

Detailed Solution

Given: The sequence 3, 9, 27, 81, ..... is a GP. Here, we have to find which term of the given sequence is 6561. Hence, 6561 is the 8th term of the given sequence.

What is an arithmetic series?

An arithmetic series is the sum of a sequence in which each term is computed from the previous one by adding (or subtracting) a constant. Discover the equations and formulas in an arithmetic series.

What is the rule of arithmetic sequence?

The Rule. Because all arithmetic sequences follow a similar pattern, you can use a general formula to find the formula for the sequence. The formula is this: an = a1 + d (n - 1)

What comes next, 1/3,9/27?

The next number in the sequence is 81.

How can I find the nth term?

To find the nth term, first identify the sequence type (like arithmetic), then use its specific formula, such as an=a1+(n−1)da sub n equals a sub 1 plus open paren n minus 1 close paren d𝑎𝑛=𝑎1+(𝑛−1)𝑑 for arithmetic sequences (where a1a sub 1𝑎1 is the first term and dd𝑑 is the common difference), or find the pattern by looking at differences and times tables to build a formula like dn+cd n plus c𝑑𝑛+𝑐.
 

What is the 25th term of this arithmetic sequence: 3, 9, 15, 21, 27?

The sequence given is 3, 9, 15, 21, 27, … Therefore, the 25th term is 147.

Is AP math hard?

In 2021, about 71% of test-takers passed AP exams with a score of 3 or higher. AP Calculus AB students had a pass rate around 61%. Because the pass rate of the AP Calculus AB exam is lower than the average pass rate across all AP classes, you could infer AP Calculus AB is more difficult than some others.

What are 5 examples for arithmetic progression?

For example, 1, 5, 9, 13, 17, 21, 25, 29, 33, ... is an arithmetic progression as the differences between every two consecutive terms are the same (as 4). i.e., 5 - 1 = 9 - 5 = 13 - 9 = 17 - 13 = 21 - 17 = 25 - 21 = 29 - 25 = 33 - 29 = ...

How to identify an AP?

Arithmetic Progressions' (AP) Properties

If 2y=x+z three numbers x,y, and z are in an A.P. If the nth the term of a sequence is a linear expression, the sequence is an A.P. If we select terms from an A.P in a regular interval, these terms will also be in AP.
