Sequences are also called progressions.
A sequence is a special set of a function from a subset
of N to R or C.
If all the members of a sequence are real numbers, then
it is called a real sequence.
Sequence is a function whose domain is a subset of the
set of natural numbers.
Sum of n A.M’s between a and b is equal to n times
their A.M.
In Geometric progression, r is the ratio of any term of
the G.P to its predecessor.
No term in geometric progression is zero.
The n geometric mean between a and b are a (b/a)n/n+1
Equivalent common fraction is also called vulgur
fraction.
Zero cannot be the term of harmonic sequence.
In sigma notation k is called index of summation.
