Hint: To answer the type of progression, we should first know what progression and series. The sequence of the variable and numbers is called a series. We know that series are made in symmetry and a progression is formed by series. We can say that a progression is a series that advances in a logical and predictable pattern.
Complete step by step answer:
We know that the progression principle states that there is a perfect level of overload in between a too slow increase or a too rapid increase. There are mainly types of progression:
Arithmetic progression: Arithmetic progression or AP is a sequence of numbers in order in which the difference of any two consecutive numbers is a constant value.
The formula for finding the term of an AP is:
,
Where we know that is the first term, is the common difference and number of terms.
We can find the sum of the term of AP by the formula:
Geometric progression: We know that geometric progression or GP is progression of numbers with a constant ratio between each number and the one before. The general form of a geometric progression is of the form;
We can calculate the term of G.P with the formula:
where is the first term and is the ratio between them.
We can calculate the sum of terms with the formula:
Harmonic progression: A harmonic progression (HP) is defined as a sequence of real numbers which is determined by taking the reciprocals of the arithmetic progression that does not contain zero. The formula of the term of the Harmonic progression is:
,
where is the first term, is the common difference and is the number of terms in AP.
We can also write the above formula as:
.
Hence these are the different types of A.P.
Note: We should note that the numbers is an arithmetic progression.These are called the Fibonacci numbers. The Fibonacci sequence is a series of numbers where a number is an addition of the last two numbers starting with and . The Fibonacci sequence can be written as:
We can write the rule of this expression as:
