What is the 33rd term of this arithmetic sequence 12 7 2 -3 -8 and?
It is -148.
How do you solve -3 6-12 24-..-a7?
The numbers could be from the sequence with a(1) = -3 and the common ratio r = (-2)If so, thena(7) = -3*(-2)^6 = -3*64 = -192.Of course, it is entirely possible that the numbers do not form a geometric sequence but a polynomial sequence such asa(n) = (27*n^3 - 189*n^2 + 396*n - 240)/2 and if so, a(7) = 1266.
Descending arithmetic sequence?
An arithmetic sequence is where a constant is added to the base case, and then added again until the proscribed limit is reached. An example is 1, 3, 5, 7, where the constant is 2 and the base case is 1. The constant can be negative, such as -4, base case 16, which leads to a descending sequence of 16 12 8 4 0 -4 -8...
The geometric mean of 3 and 48 is -12?
No, it is 12.
What is the geometric mean of 36 and 4?
12
Which explains why the sequence 216 12 23 is arithmetic or geometric?
The sequence 216 12 23 is neither arithmetic nor geometric.
Is 20 12 62 a geometric or arithmetic sequence?
It is neither.
Is 3 6 12 24 48 an arithmetic sequence?
No, geometric, common ratio 2
Is the sequence 2 3 5 8 12 arithmetic or geometric?
It is neither. It is a quadratic sequence. Un = (x2 - x + 4)/2 for n = 1, 2, 3, ...
How do you cheat on Plato web pre-algebra?
What is the eighth term of the geometric sequence 3, 12, 48, 192, ... ?
Is geometric sequence a sequence in which each successive terms of the sequence are in equal ratio?
Yes, that's what a geometric sequence is about.
Given the geometric sequence 3 12 48 192 what term number is 12 288?
The factor is 4. 12288/192 = 64 ie 4 cubed, so it is the next term but two, ie the seventh. (192, 768, 3072, 12288)
Is this arithmetic 0.75 3 12 48 and what are the next two numbers?
That series of numbers is a geometric progression. Each successive number is multiplied by 4. Therefore, after 12 x 4 = 48 comes 48 x 4 = 192, and after 192 comes 192 x 4 = 768.
What is the formula for the following arithmetic sequence?
12, 6, 0, -6, ...
What is descending geometric sequence?
A geometric sequence is a sequence where each term is a constant multiple of the preceding term. This constant multiplying factor is called the common ratio and may have any real value. If the common ratio is greater than 0 but less than 1 then this produces a descending geometric sequence. EXAMPLE : Consider the sequence : 12, 6, 3, 1.5, 0.75, 0.375,...... Each term is half the preceding term. The common ratio is therefore ½ The sequence can be written 12, 12(½), 12(½)2, 12(½)3, 12(½)4, 12(½)5,.....
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 common ratio in this geometric sequence 3 12 48?
The ratio is 4.
