1.1 Conducting mathematical operations with exponential numbers and expressing them in terms of a x (bk) where a ranges from 0 < a < 10.
1.2 Sequence- A sequence is a list of numbers that is written in a defined order, ascending or descending, following a specific rule.

Series- A series is the sum of all the terms in a sequence.

A finite sequence has a fixed number of terms.

An infinite sequence has an infinite number of terms.

A term in a sequence is named using the notation 𝑎𝑛, where 𝑛 is the position of the term in the sequence.

A term in a sequence is named using the notation 𝑎𝑛, where 𝑛 is the position of the term in the sequence.

A sequence formed when each term after the first is found by adding a fixed non-zero number is called an arithmetic sequence.

Adding up the terms of an arithmetic sequence gives us arithmetic series.

1.3 A sequence in which every term is obtained by multiplying or dividing a non-zero number with the preceding number is known as a geometric sequence.

When 𝑟 > 1, the sequence is diverging.
And when 𝑟 < 1, the sequence is converging.

A geometric series with 𝑟 < 1 and with infinite number of terms is called an infinite geometric series.
