Question

arthemetic progression​

Answer 1

Answer:

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:

An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same. ... For example, the sequence 2, 6, 10, 14, … is an arithmetic progression (AP) because it follows a pattern where each number is obtained by adding 4 to its previous term. In this sequence, nth term = 4n-2.
