➡Arithmetic Progression .

Arithmetic progression or Arithmetic Sequence is a sequence of number such that the different between the consiqutive term is constant .

Different here means , the second minas the first.

➡Example :-

Let, 3,5,7,9,11.......are In A.P.

↪So, Common difference will be

= 5-3

= 2.

➡Formula :-

↪an = a1 + (n-1)d .

where,

↪an = the nth terms in the sequence .

↪a1= first term in the sequence .

↪d=Common difference .
