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
This is not a geometric series since -18/54 is not the same as -36/12
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
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.
Even numbers. A geometric progression where each number is three times the previous number.
Expressed as a percentage, 54/18 x 100 = 300 percent.
This is not a geometric series since -18/54 is not the same as -36/12
The geometric mean of 18 and 54 is 31.176914
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
18
Each number is 3 times the previous number so they would be 162, 486, and 1,458.
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 arthmetic sequence of 1 6 3 18 54 27 ? what is the missing terms ?
It could be -3 or +3.
-2
Each term is 3 times greater than the previous term and so the next term will be 486
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
6, 2, ⅔
