How can you get the common difference in an arithmetic sequence?
You subtract any two adjacent numbers in the sequence. For example, in the sequence (1, 4, 7, 10, ...), you can subtract 4 - 1, or 7 - 4, or 10 - 7; in any case you will get 3, which is the common difference.
Determine if the sequence below is arithmetic or geometric and determine the common difference/ ratio in simplest form 300,30,3?
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 10.
Is -22 -10 2 14 an arithmetic sequence?
Yes.
What is the Th term of the arithmetic sequence given by the explicit rule?
The answer depends on what the explicit rule is!
Answer for nth term 10 6 2 -2 -6?
The given sequence is an arithmetic progression.a = first term of A.P. = 10, d = common difference = an - an-1 = -4nth term of an A.P. is given by: an = a+(n-1)dPlugging in the values we get an = 10+(n-1)(-4) = 10 - 4n + 4 = 14 - 4n.

What is the tenth number in the sequence 1 -17 -35 -53?
This is an arithmetic sequence with t1 = 1 and the common difference d = -18.The nth term of an arithmetic sequence is given by the formula:tn = t1 + (n - 1)d (substitute 10 for n, 1 for t1, and -18 for d)t10 = 1 + (10 - 1)(-18) = 1 + 9(-18) = 1 - 162 = -161Thus the 10th number of the sequence is -161.
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.
Is negative 2 3 8 10 an arithmetic sequence?
Nope, bc the common difference is not constant ( linear) its goes up +1, +5, +2, therefore, again, it's not constant
Is this an arithmetic sequence or a geometric sequence 13 23 33 43 53?
Arithmetic- the number increases by 10 every term.
What is the diffeence between the term to term rule and the common difference in maths?
The common difference does not tell you the location of the sequence. For example, 3, 6, 9, 12, ... and 1, 4, 7, 10, .., or 1002, 1005, 1008, 1011, ... all have a common difference of 3 but it should be clear that the three sequences are different. A common difference is applicable to arithmetic sequences, not others such as geometric or exponential sequences.
Is this sequence 10 10.25 10.50625 10.76890625 arithmetic?
No, it is geometric, since each term is 1.025 times the previous. An example of an arithmetic sequence would be 10, 10.25, 10.50, 10.75, 11.
Is -22 -10 2 14 an arithmetic sequence?
Yes.
What is the Th term of the arithmetic sequence given by the explicit rule?

Is one one fourth one seventh one tenth a arithemtic sequence?
An arithmetic sequence is a sequence of numbers where the difference is constant. The difference between 1 and 1/4 is 3/4. The difference between 1/4 and 1/7 is 3/28. The difference between 1/7 and 1/10 is 3/70. These differences are not constant.
