This tool is used to calculate the sum of n terms in an arithmetic sequence and find the arithmetic of the NTH term. A series is a series of Numbers arranged in a certain order according to certain rules. And if each term in a series differs by a constant from the previous term, then such a series is called arithmetic series with different constants and AP is called the common difference, expressed by d. The first term of AP and the common difference d is given
A, (a + d), (a + 2d),…
The NTH term of the arithmetic sequence obtained from the formula
Tn = a + (n – 1) d
TN is the value of the previous term
D is the AP for tolerance
A is the AP of the first value
From the formula, we can get the sum of n items in an arithmetic sequence
N is the total number of terms. When it comes to online calculations, this arithmetic series calculator can help you calculate the sum of the NTH term and an AP n term.
