Best Answer

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

What is the nth term of the arithmetic sequence 7101316?

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


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 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.

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.
