## What is a non trivial arithmetic sequence?

“Non-trivial” just means “non-constant”. That is, a non-trivial three-term arithmetic progression is a triple of elements of the form (a,a+b,a+2b) where b≠0 (the b≠0 condition being what makes it “non-trivial”).

What is non trivial example?

A solution or example that is not trivial. Often, solutions or examples involving the number zero are considered trivial. Nonzero solutions or examples are considered nontrivial. For example, the equation x + 5y = 0 has the trivial solution (0, 0). Nontrivial solutions include (5, –1) and (–2, 0.4).

### What is non arithmetic progression?

An arithmetic sequence, also known as an arithmetic progression, is a finite sequence of at least three numbers, or an infinite sequence, whose terms differ by a constant, known as the common difference. This gives the non-arithmetic sequence 0, 1, 3, 4, 9, 10, 12, 13, 27, 28.

Which of the following is not arithmetic sequence?

The following are not examples of arithmetic sequences: 1.) 2,4,8,16 is not because the difference between first and second term is 2, but the difference between second and third term is 4, and the difference between third and fourth term is 8. No common difference so it is not an arithmetic sequence.

## How are arithmetic sequences related to real life?

Arithmetic sequences are used in daily life for different purposes, such as determining the number of audience members an auditorium can hold, calculating projected earnings from working for a company and building wood piles with stacks of logs.

What is non trivial problem?

Often used as an understated way of saying that a problem is quite difficult or impractical, or even entirely unsolvable (“Proving P=NP is nontrivial”). The preferred emphatic form is decidedly nontrivial. See trivial, uninteresting, interesting.

### What are non trivial factors?

(A nontrivial factor is a factor other than 1 and the number). Thus 6 has two nontrivial factors. Now, 2 is a factor of 6. Thus the number of nontrivial factors is a factor of 6. Hence 6 is a Bishal number.

What is arithmetic and non arithmetic sequence?

An arithmetic sequence is a sequence (list of numbers) that has a common difference (a positive or negative constant) between the consecutive terms. No common difference so it is not an arithmetic sequence.

## Is it possible to have an arithmetic sequence that is non decreasing but not increasing?

Indeed, it is not increasing or non-decreasing because the second term (when n = 1) is less then the first term (when n = 0), so the sequence drops there; and it is not decreasing or non-increasing because the third term is greater than the second term, so the sequence increases there.

What is an arithmetic sequence give an example of a sequence which is not arithmetic?

The sequence 21, 16, 11, 6 is arithmetic as well because the difference between consecutive terms is always minus five. The sequence 1, 2, 4, 8 is not arithmetic because the difference between consecutive terms is not the same.

### How important are arithmetic sequences in solving real life problems?

The arithmetic sequence is important in real life because this enables us to understand things with the use of patterns.

What are the problems in arithmetic sequence?

WORD PROBLEMS IN ARITHMETIC SEQUENCE. Problem 1 : In a winter season let us take the temperature of Ooty from Monday to Friday to be in A.P. The sum of temperatures from Monday to Wednesday is 0° C and the sum of the temperatures from Wednesday to Friday is 18° C. Find the temperature on each of the five days.

How do you find the number of terms in an arithmetic sequence?

Formula to find number of terms in an arithmetic sequence : n = [ (l – a1) / d] + 1. Substitute 483 for l, 7 for a1 and 4 for d. n = [ (483 – 7) / 4] + 1. n = [476 / 4] + 1. n = 119 + 1. n = 120. Therefore, there are 120 terms in the given arithmetic sequence.
