At the informal level, students use the context of songket Palembang to find rules of arithmetic sequence and series. In preformal level, students begin composing and drawing motif images of songket as of arithmetic sequences, using pieces of motifs songket as a model of what they consider to...
Sequence 和 Progression(AP) 意思基本上是一样的，都是 a sequence of numbers 。Series 指的是序列中每个元素的「和」(SUM)，比如Fourier series 傅里叶级数，等差数列的SUM叫做「算术级数」(arithmetic series),等比数列的叫做「几何级数」(geometrical progression).Sequence 、Progression序列 Seq...
An arithmetic series is the sum of an arithmetic sequence. We find the sum by adding the first, a1 and last term, an, divide by 2 in order to get the mean of the two values and then multiply by the number of values, n:ExampleFind the sum of the following arithmetic series 1,2,3...

, so the sum of the first n terms of the arithmetic series, S, is equal to one-half the number of terms multiplied by the sum of the first and last terms. That is, . Find the sum of the terms in the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. ...
An arithmetic series is the sum of the terms in an arithmetic sequence with a definite number of terms. Following is a simple formula for finding the sum:
Let's say we have the simplest of arithmetic sequences. {1,2,3,⋅⋅⋅,n}{1,2,3,⋅⋅⋅,n} And what I want to think about is what is the sum of this sequence going to be? And the sum of a sequence, we already know we call a series as following: ...
