Introduction

        Logarithm is defined as the exponent that indicates the power to which a base number is raised to produce a given number. In this assignment I shall attempt to investigate the characteristics of sequences of logarithms. As a conclusion, I will try to find the general statement and finally the range and limitations of a, b and x will be considered.

Write down the next two terms of each sequence

The given examples of logarithms are as follows:

It can be easily noticed that in each sequence every term has the same number of logarithms, ...
