Question

what is the formula of AP​

Answer 1

Step-by-step explanation:

Formula Lists

General Form of AP a, a + d, a + 2d, a + 3d, . . .

The nth term of AP an = a + (n – 1) × d

Sum of n terms in AP S = n/2[2a + (n − 1) × d]

Sum of all terms in a finite AP with the last term as 'l' n/2(a + l)

Answer 2

Answer:

There are two major formulas we come across when we learn about Arithmetic Progression,(AP)which is related to:

The nth term of AP

Sum of the first n terms

The Nth Term Of Ap Formula-

an = a + (n − 1) × d

Sum of the first n terms Formula

S = n/2[2a + (n − 1) × d]
