Question

write the ap use of formula

Answer 1

If you have the sequence 2, 8, 14, 20, 26, then each term is 6 more than the previous term. This is an example of an arithmetic progression (AP) and the constant value that defines the difference between any two consecutive terms is called the common difference.

If an arithmetic difference has a first term a and a common difference of d, then we can write

a, (a + d), (a + 2d),... {a + (n-1) d}

where the nth term = a + (n−1)d
