Since the difference of all the two consecutive terms of the sequence is equal, we can say that the common difference is 5. nth term– the nth term of an arithmetic sequence is any term of the sequence which is not given in the sequence. Thenth term of an arithmetic sequence is defined...
当然,这些sequences都是Arithmetic sequences,它们都有一个共同的特点,那就是每个数列的任意相邻两项之差都是相同的。我们不妨用 和 来表示相邻两项,那么: 其中,d为common difference。 上面这个式子,我们称之为recurrence formula,也就是用这种关系式来描述相邻两项或相邻几项之间的关系。 提个问题,我们能够用它...
Arithmetic Sequence Formula Arithmetic Sequence Examples and Rules Lesson Summary Frequently Asked Questions What are examples of arithmetic sequences? An arithmetic sequence is a list of numbers that can be generated by repeatedly adding a fixed value, which determines the difference between consecutive...
Learn the Arithmetic sequence formula and meaning. Discover how to find the common difference and read arithmetic sequence examples.
An arithmetic sequence is a sequence where each term is found by adding or subtracting the same value from one term to the next. This value that is added or subtracted is called "common sum" or "common difference" If the common difference is positive, the terms of the sequence will increa...
