Question

hi please say about ap arithmetic progression ​

Answer 1

definition:

a sequence a1,a2,a3......an,....is called an arithmetic mean.

a1 is called the first term and the constant d is called as common difference.

an+1=an+d,n belongs to N

an= a+(n-1)d

so the A.P,looks like

a,a+d,a+2d,a+3d......,a+(n-1)d,a+nd,.....

General formula:

th=a+(n-1)d,then n belongs to N.
