2. What is Sequence and Series?

A "sequence" is nothing but an ordered list of numbers. The numbers that are present in the ordered list are called as "elements" or "terms" of the sequence. When you add up all the terms in a sequence, you get a "series"; the addition, as well as the resulting value, is called the "sum" or "summation." For example, the sequence "1, 2, 3, 4" contains the terms "1", "2", "3", and "4"; the corresponding series is the sum "1 + 2 + 3 + 4", and the series' value is 10.

5. Which concepts are discussed in this chapter?

The relevance of sequences,' which play a key part in a range of human activities, is explained in chapter 8 Sequences and Series. In our daily lives, we encounter many examples of sequences, such as the human population, money placed in banks, the value of any product over some time, and so on. When a collection is arranged in such a way that its members are labeled as first, second, third, and so on, it is said to be listed in the form of a sequence.'

6. Write the first five terms of the sequences and obtain the corresponding series:

a1 = -1, an = an-1/n, n ≥ 2

a1 = -1, an = an-1/n, n ≥ 2

Given, an = an-1/n and a1 = -1

Then,

a2 = a1/2 = -½

a3 = a2/3 = -⅙

a4 = a3/4 = -1/24

a5 = a4/5 = -1/120

Thus, the first 5 terms we obtained are -1, -½, -⅙, -1/24, -1/120.
