We also know that the first term is 1, and the last term is 101. But we do not know how many terms are in the series. So we will need to use the formula for the last term of an arithmetic progression, ℓ = a + (n − 1)d to give us 101 = 1 + (n − 1) × ...
答:算术级数增长与几何级数增长原本来源于马尔萨斯的人口理论。其中算术级数增长是指随着时间的推移,每年增加的数目是固定的,历年的总数目排列为等差数列的形式,假设第一年基数为2,每年固定增长的数目为1,则第二年增长的总人数则为3,以此类推。几何级数增长是指随着时间的推移,其增长数目是按几何级数增加,历年的总数...
In this article, we will explore the concept of arithmetic progression, the AP formulas to find its nthterm, common difference, and the sum of n terms of an AP. We will solve various examples based on the arithmetic progression formula for a better understanding of the concept. What is Ar...

When the first and last terms are given, the formula of the sum of the first n terms of the arithmetic progression is given bySn = n/2 ( first term + last term )For example, let us use the previously given sum of the first 50 natural numbers. Since the given tells that the first...

Geometric progression with an infinite number of terms and a common factor less than 1 can be calculated by the following formula −S=a1−rS=a1−r, where “a” is the first term, “r” is the common factor.4. What is the difference between a sequence and a series?
Explore Arithmetic and Geometric Progression, a part of sequence and series. Learn how to calculate the nth term of any series and also the sum of the n terms in any given series.
is geometric with a=1 and r=2. The value of the 10th term, i.e., when n=10, is given as 1·210−1=29=512. The sum of the geometric progression is given by the formula a(1−rn)/(1−r) for the first n terms. A harmonic progression is one in which the terms are the...
