The arithmetic progression is a kind of common sequence. If a sequence is from the second term, the difference between each term and its previous term is equal to the same constant. The sequence is called the arithmetic progression, and the constant is called the arithmetic progression. Tolerances, tolerances are often indicated by the letter d. For example: 1,3,5,7,9...1+2(n-1). The general formula of the arithmetic progression is: an=a1+(n-1)d (1) The first n terms and the formula are: or Sn=n(a1+an)/2. Note: The above n are all positive integers.

English Arithmetic Progression referred to as AP Chinese: arithmetic progression. Is an online tool for calculating the sum of n items of an arithmetic progression and finding the arithmetic of the nth term. A series is a series of numbers that are arranged in a certain order according to certain rules. If each item in a series differs from the previous item by a constant, then such a series is called an arithmetic level and an AP with a constant constant is called a common difference, denoted by d. AP first item and common difference d are given   a, (a + d), (a + 2d), ...

The nth item of the arithmetic progression column that can be derived from the formula

Tn = a + (n-1)d lazy calculator

TN represents the previous value

d indicates the tolerance of the AP

a indicates the AP of the first value From the formula, we can get the sum of n items of an arithmetic progression \(S_n = \frac {n}{2} (First term + Last term)\)

n represents the total number of items. When it comes to online calculations, this arithmetic progression calculator can help you calculate the sum of the nth term and an AP n term.
