- 1> An Arithmetic Progression (A.P.) is a sequence in which difference between any two consecutive terms is constant. >Second term-First term=Third term-Second term=Common difference(d). >common difference = d = a1 - a2 > General form = a, a+d, a+2d...> a1 = a2 - d
>an = a + (n-1)d
>nth term from end= l - (n-1)d
l = last term of A.P.
> sum of n terms of A.P.
> If a constant is added, subtracted, multiplied or divided by each term of an A.P., the result will also be an A.P. - 2—
