Question

any body can tell all the formulas of the chapter ARITHMETIC PROGRESSIONS (10th standard)​

Answer 1

Answer:

an=a1+(n-1)d

Step-by-step explanation:

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tn = nth term and a = first term. ... The sum of n terms is also equal to the formula where l is the last term.

Answer 2

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)
