Grade 12 Mathematics
Definition of logarithms - correct answer-The logarithm of a number is the value to which the
base must be raised to give that number i.e. the exponent. From the first example of the
activity log2(4) means the power of 2 that will give 4. As 22=4
Laws of logarithms - correct answer-Just as for the exponents, logarithms have some laws
which make working with them easier. These laws are based on the exponential laws and
are summarized first and then explained in detail.
Arithmetic sequence - correct answer-An arithmetic (or linear) sequence is a sequence of
numbers in which each new term is calculated by adding a constant value to the previous
term
Geometric sequences - correct answer-A geometric sequence is a sequence of numbers in
which each new term (except for the first term) is calculated by multiplying the previous term
by a constant value.
Series - correct answer-In this section we simply work on the concept of adding up the
numbers belonging to arithmetic and geometric sequences. We call the sum of any
sequence of numbers a series.
