What is the sequence of 10 8 6 4?
10-2x for x = 0, 1, 2, 3, ... Since the domain of an arithmetic sequence is the set of natural numbers, then the formula for the nth term of the given sequence with the first term 10 and the common difference -2 is an = a1 + (n -1)(-2) = 10 - 2n + 2 = 12 - 2n.
What is the 20th term for the sequence 3 6 9 12?
It is 60.
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...
What is the nth term of this sequence 2 7 12 17 22?
5
What is the value of the 11th term in the sequence -3 -6 -12 -24 ...?
It is: -3072
WHAT IS THE Th TERM IN AN ARITHMETIC SEQUENCE WHOSE Th TERM IS -25 AND HAS A COMMON DIFFERENCE -12?
-13
Which explains why the sequence 216 12 23 is arithmetic or geometric?
The sequence 216 12 23 is neither arithmetic nor geometric.
What is the nth term of the following arithmetic sequence 12 16 20 24 28?
8 + 4n
What is the value of the nth term in the following arithmetic sequence 12 6 0 -6 ...?
18 - 6n
What is the d value of the following arithmetic sequence 16 9 2 5 12 19?
The sequence in the question is NOT an arithmetic sequence. In an arithmetic sequence the difference between each term and its predecessor (the term immediately before) is a constant - including the sign. It is not enough for the difference between two successive terms (in any order) to remain constant. In the above sequence, the difference is -7 for the first two intervals and then changes to +7.
What is the 43rd term of an arithmetic sequence with a rate of increase of -6 and a11 12?
If a11 = 12 then a43 = a11 + 32*d = 12 + 32*(-6) = -180.
What is a non arithmetic sequence?
An arithmetic sequence in one in which consecutive terms differ by a fixed amount,or equivalently, the next term can found by adding a fixed amount to the previous term. Example of an arithmetic sequence: 2 7 12 17 22 ... Here the the fixed amount is 5. I suppose any other type of sequence could be called non arithmetic, but I have not heard that expression before. Another useful kind of sequence is called geometric which is analogous to arithmetic, but multiplication is used instead of addition, i.e. to get the next term, multiply the previous term by some fixed amount. Example: 2 6 18 54 162 ... Here the muliplier is 3.
What is the formula for nth term?
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
Is 20 12 62 a geometric or arithmetic sequence?
It is neither.
What is the formula for the following arithmetic sequence?
12, 6, 0, -6, ...
What is the sum of the first 12 terms of the arithmetic sequence?
The sum of the first 12 terms of an arithmetic sequence is: sum = (n/2)(2a + (n - 1)d) = (12/2)(2a + (12 - 1)d) = 6(2a + 11d) = 12a + 66d where a is the first term and d is the common difference.
What is the twenty third term of the arithmetic sequence 6 9 12?
The nth term is 3(n+1). The twenty-third term is equal to 3 x (23 + 1) = 72
