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

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


Why does the nth term of arithmetic sequence work?

How to find the 5th term in an arithmetic sequence using the explicit rule?

Nth number in an arithmetic series equals 'a + nd', where 'a' is the first number, 'n' signifies the Nth number and d is the amount by which each term in the series is incremented. For the 5th term it would be a + 5d

what is the nth term of 13, 16, 19, 22?

The nth term of an arithmetic sequence is given by. an = a + (n โ€“ 1)d. The number d is called the common difference because any two consecutive terms of an. arithmetic sequence differ by d, and it is found by subtracting any pair of terms an and. an+1.


What sequence is formed by subtracting each term of a sequence from the next term?

It is the sequence of first differences. If these are all the same (but not 0), then the original sequence is a linear arithmetic sequence. That is, a sequence whose nth term is of the form t(n) = an + b


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.
