Question

give all the formula of Ap class 10th....​

Answer 1

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

Here u go

The formulae are as follows:

1) an=a+(n-1)d

2) Sn=n/2[2a+(n-1)d]

3)Sn=n/2(a+an)

4)Sn=n/2(a+l)

5)Sn=n(n+1)/2

Hope it helps u....
