It is represented in the form as f(x)=Ax^2+Bx+C, where A, B, C are constants. It is also called a quadratic polynomial.Į.g. Second Degree Polynomial: It is a polynomial where the highest degree of a polynomial is 2. Sequence of Prime Numbers: A prime number is a number that is not divisible by any other number except one & that number, this sequence is infinite, never-ending.Į.g. Formula is given by an = an-2 + an-1, n > 2 Suppose in a sequence a1, a2, a3, …., anare the terms & a3 = a2 + a1 & so on…. Where a2 = a1 + d a3 = a2 + d & so on…įibonacci Sequence: A sequence in which two consecutive terms are added to get the next consecutive 3rd term is called Fibonacci Sequence.Į.g.
Arithmetic number sequence series#
Harmonic series looks like this 1/a1, 1/a2, 1/a3, ……. Harmonic Sequence: It is a series formed by taking the inverse of arithmetic series.Į.g.
Suppose in a sequencea1, a2, a3, …., anare the terms & ratio between each term is ‘r’, then the formula is given byan=(an – 1) × r Geometric Sequence: A sequence in which every successive term has a constant ratio is called Geometric Sequence.Į.g. Suppose in a sequence a1, a2, a3, …., an are the terms & difference between each term is ‘d’, then the formula is given by an = a1 + (n−1)d What are the Different Types of Sequences?Īrithmetic sequence: A sequence in which every successive term differs from the previous one is constant, is called Arithmetic Sequence.Į.g. The sequence is a collection of objects in which repetitions are allowed and order is important.
