tn = a + (n - 1)d

where a is the first term and d is the difference between each term.

### How do you use a arithmetic sequence to find the nth term?

The difference between successive terms in an arithmetic sequence is a constant. Denote this by r. Suppose the first term is a. Then the nth term, of the sequence is given by t(n) = (a-r) + n*r or a + (n-1)*r

### Rule to finding terms in a arithmetic sequence?

The nth term of an arithmetic sequence = a + [(n - 1) X d]

### Which rule will find the nth term of the arithmetic sequence -58 -65 -72 -86?

It appears that a number of -79 is missing in the sequence and so if you meant -58 -65 -72 -79 -86 then the nth term is -7n-51 which makes 6th term in the sequence -93

### What is the nth term of the arithmetic sequence 7101316?

One number, such as 7101316 does not define a sequence.

### What is an nth term in an arithmetic sequence?

The nth term is referring to any term in the arithmetic sequence. You would figure out the formula an = a1+(n-1)d-10where an is your y-value, a1 is your first term in a number sequence (your x-value), n is the term you're trying to find, and d is the amount you're increasing by.

### nth term of 7.14.21.28.35?

The given sequence (7, 14, 21, 28, 35,....) is an arithmetic sequence where each term increases by 7. The nth term of the given sequence is 7n

### Why does the nth term of arithmetic sequence work?

Because that is how it is defined and derived.

### What is the nth term in the arithmetic sequence?

It is a + 8d where a is the first term and d is the common difference.

### What is the nth term for 26 18 10 2 -6?

The nth term in this arithmetic sequence is an=26+(n-1)(-8).

### What is the nth term in the arithmetic sequence 0.87 1.24 1.61 1.98?

It is: 0.37*term+0.5

### What is the nth term for 1 7 13 19?

The given sequence is an arithmetic sequence with a common difference of 6. To find the nth term of this sequence, we can use the following formula: nth term = first term + (n - 1) x common difference where n is the position of the term we want to find. In this sequence, the first term is 1 and the common difference is 6. Substituting these values into the formula, we get: nth term = 1 + (n - 1) x 6 nth term = 1 + 6n - 6 nth term = 6n - 5 Therefore, the nth term of the sequence 1, 7, 13, 19 is given by the formula 6n - 5.
