In this section, we are going to see some example problems in arithmetic sequence. General term or n th term of an arithmetic sequence : a n = a 1 + (n - 1)d. where 'a 1 ' is the first term and 'd' is the common difference. Formula to find the common difference : d = a 2 - a 1. Formula to find number of terms in an arithmetic sequence :
Arithmetic Sequences Practice Problems and Solutions. When I work with arithmetic sequences, I always keep in mind that they have a unique feature: each term is derived by adding a constant value, known as the common difference, to the previous term. Let’s explore this concept through a few examples and problems.

Problem 1: Find the 10 th term of the arithmetic sequence where the first term a 1 is 5 and the common difference d is 3. Solution: Using the formula for the nth term of an arithmetic sequence: a n = a 1 + (n - 1)d. For the 10th term (\(n = 10\)): a 10 = 5 + (10-1) × 3
Because the sequences are arithmetic progressions, we can use the formula to find sum of 'n' terms of an arithmetic series. = 2 x (n/2)[a + l] Substitute n = 12, a = 1 and l = 12. = 2 x (12/2)[1 + 12] = 12[13] = 156. Therefore the clock will strike 156 times in a day. Problem 4 :

The Definition of an Arithmetic Sequence. An arithmetic sequence is a series of numbers where the difference between neighboring numbers is constant. For example: 1, 3, 5, 7, 9, ... Is an arithmetic sequence because 2 is added every time to get to the next term. The difference between neighboring terms is a constant value of 2.

Solving problems involving arithmetic sequences. There are many problems we can solve if we keep in mind that the nth term of an arithmetic sequence can be written in the following way: a n = a 1 +(n - 1)d Where a 1 is the first term, and d is the common difference. For example, if we are told that the first two terms add up to the fifth term, and that the common difference is 8 less than the ...
This document provides examples of arithmetic sequence problems with solutions. It defines arithmetic sequences and provides the formulas for finding the nth term and sum of terms. It then works through several example problems, finding terms, differences, sums, and developing formulas for arithmetic sequences given various conditions. The examples cover a range of arithmetic sequence ...
