sum of ap series

Formula for Arithmetic Progression (AP)

Here you you will learn what is arithmetic progression (AP) and formula for arithmetic progression. Let’s begin – Arithmetic Progression (AP) A sequence is called an arithmetic progression if the difference of a term and the previous term is always same  i.e.  $$a_{n+1}$$ – $$a_n$$ = constant (=d) for all n $$\in$$ N The constant …

Formula for Sum of AP Series | Properties of AP

Here, you will learn what is arithmetic progression (ap) and formula for sum of ap series and properties of ap. Let’s begin – The indicated sum of the terms of a sequence. In the case of a finite sequence $$a_1$$, $$a_2$$, $$a_3$$,………,$$a_n$$ the corresponding series is $$a_1$$ + $$a_2$$ + $$a_3$$ + ……… + $$a_n$$ …
