Question

please define arithmetic progression in (short )

Answer 1

An arithmetic progression is a sequence of numbers such that the difference of any two successive members is a constant. For example, the sequence 1, 2, 3, 4, ... is an arithmetic progression with common difference 1.

Answer 2

$\textbf{Answer :}$




$\huge\textbf{Arithmetic progression :}$




It is a sequence of numbers in which the different between two consecutive terms is constant.

====================================



$\huge\textbf{Example :}$




a, a + d, a + 2d, a + 3d ....... (and so on).




→ 2, 4, 6, 8, 10....

In this d = 2

2, 2 + 2, 2 + 2(2), 2 + 3(2), 2 + 4(2)....

2, 4, 2 + 6, 2 + 8....

So, the arithmetic progression came is 

2, 4, 6, 8, 10....




→ 4, 8, 12, 16, 20.....

In this d = 4



→ 9, 18, 27, 36, 45, 54 ....

In this d = 9
