In my previous posts, I discussed about finding nth term of arithmetic progression. In this post, I will be discussing about how to find sum of n terms of arithmetic progression. Lets take an example. We have an arithmetic progression of the form … [Continue reading]
How to Solve Quadratic Equations using Quadratic Formula?
Quadratic Equation is the equation of the form $$ax^2+bx+c=0$$ where $$a \ne 0$$ or which can be converted to this form. This form of quadratic equation is also called standard form. If we have quadratic equation $$x^2+6x+8=0$$. Comparing it with … [Continue reading]
What is an Arithmetic Sequence?
What is an Arithmetic Sequence or an Arithmetic Progression? Arithmetic Sequence is a sequence in which difference between any two consecutive terms is constant. For example, we have sequence: 5, 8, 11, 14, 17, 20, 23. The difference … [Continue reading]
What is a Geometric Progression?
Geometric progression is the progression in which every next term is found by multiplying the previous term by a fixed number. In other words, we can say that it is the progression in which any term divided by previous term always remain constant. … [Continue reading]
What are perfect square numbers?
A natural number m is called a perfect square number if it can be expressed as $$n^2$$ where n is also a natural number. For example, 4 is a perfect square number because it is a natural number and it can be expressed as $$2^2$$ and 2 is also a … [Continue reading]
