Introduction to Arithmetic progression:

In this article, we will discuss about arithmetic progression. Progressions are of two types .They are arithmetic and geometric progression. An Arithmetic progression which consists of the sequence of numbers and the terms except the first can be obtained by adding one number to its preceding number. Arithmetic progression is denoted as the arrangement of two consecutive numbers, the progression which is constant.

Example Problems for Arithmetic Progression

Example :

The sequence terms of an A.P. 6, 1, –4...Find the 10th term.Do you need help with algebra expressions

Solution:

Consider the A.P in the form a, a + d, a + 2d, ...

Here, a = 6, d = 1 – 6 = –5, n = 12

t_n = a + (n–1) d You can also look Vast math knowledge

t₁₀ = 6 + (10 – 1) (–5) = 6 + 9 x (–5) = 6 – 45 = – 39 , ∴ The 12th term is –39.
