/ ตัวเอียง คือ Subordinate clause ครับ ....
1. An arithmetic sequence is a sequence ..... in which, beginning with the second term, each term is found by adding the same value to the previous term.
2. Its general term is described by an = a1 + d (n–1). The number "d" is called the common difference .... which can be found by taking any term in the sequence and subtracting its preceding term.
3. The sum of the members of a finite arithmetic sequence is called an arithmetic series .... about which we are writing sentences.
4. Sn = n (a1+an) / 2 .... if Sn represents the sum of an arithmetic sequence with terms a1 , a2 , a3 ,.... an accordingly.
5. This is the trick .... which Gauss used as a schoolboy to solve the problem of summing the integers from 1 to 100 given as busy-work by his teacher.

6. A "sequence" is an ordered list of numbers .... which are called the "elements" or the "terms" of the sequence.
7. To indicate a series, we use either the Latin capital letter "S" or else the Greek letter corresponding to the capital "S", .... which is called "sigma" (SIGG-muh) ------> ∑
8. There are some rules .... that can help simplify or evaluate series.
9. If every term in a series is multiplied by the same value .... You can factor this value out of the series ------> ∑c⋅an = c⋅∑an
10. The other rule for series is .... that, if the terms of the series are sums, then you can split the series of sums into a sum of series. ------> ∑(ak + bk) =∑ak + ∑bk
