a(n) = a(1) x r^n-1
In this case a(1) is 2 and r is 3
That makes the formula a(n) = 2 x 3^n-1

What is the r value of the following geometric sequence -81 54 -36 12?
This is not a geometric series since -18/54 is not the same as -36/12
What is the r value of the following sequence 6 -18 54 -162?
To find the common ration in a geometric sequence, divide one term by its preceding term: r = -18 ÷ 6 = -3 r = 54 ÷ -18 = -3 r = -162 ÷ 54 = -3
Two geometric means between 2 and 54?
Look 2 and 8, their geometric mean is square root of 16 which is 4 and between 2 and 54. 9 and 4 have a geometric mean of 6 which is also between 2 and 54. Is this what you mean? Pun intended... The geometric mean of 2 and 54 is square root of 108.
The numbers 2 6 18 54 are examples of what?
Even numbers. A geometric progression where each number is three times the previous number.
What is 18 percent of 54?
Expressed as a percentage, 54/18 x 100 = 300 percent.
What is the r value of the following geometric sequence -81 54 -36 12?
This is not a geometric series since -18/54 is not the same as -36/12
What is the geometric mean of 18 and 54?
The geometric mean of 18 and 54 is 31.176914
What is the r value of the following sequence 6 -18 54 -162?
To find the common ration in a geometric sequence, divide one term by its preceding term: r = -18 ÷ 6 = -3 r = 54 ÷ -18 = -3 r = -162 ÷ 54 = -3
What is the geometric mean of 54 and 6?
18
What are the next three terms in the geometric sequence 2 6 18 54?
Each number is 3 times the previous number so they would be 162, 486, and 1,458.
What is the sixth term of the geometric sequence 61854?
If you mean 6, 18, 54 then the 6th term is 1456 because each term is 3 times greater than the previous term
What is the pattern sequence of 1 6 3 18 54 27?
what is the arthmetic sequence of 1 6 3 18 54 27 ? what is the missing terms ?
What is the common ratio of the geometric sequence whose second and fourth terms are 6 and 54 respectively?
It could be -3 or +3.
What is the next term in the following sequence 54 -18 6?
-2
What is the explicit formula for this sequence 2 6 18 54 162?
Each term is 3 times greater than the previous term and so the next term will be 486
What number comes next in the sequence 243 81 27?
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
What is the next 3 numbers in the sequence 486 162 54 18?
6, 2, ⅔
