Expert-Verified Answer A sequence of numbers are said to form an Arithmetic progression if the difference between any two consecutive terms is always the same. Here the given progression is 2 , 2 , 2 , 2 , . . . . So the given progression is an arithmetic progression.

An arithmetic sequence is an ordered set of numbers that have a common difference between each consecutive term. For example in the arithmetic sequence 3, 9, 15, 21, 27, the common difference is 6. An arithmetic sequence can be known as an arithmetic progression.

The arithmetic sequence formula refers to the formula to calculate the general term of an arithmetic sequence and the sum of the n terms of an arithmetic sequence. The general term of an arithmetic sequence is, an = a1 + (n - 1) d. The sum of the first 'n' terms of an arithmetic sequence is, n = (n/2) [2a1 + (n - 1) d]

An example of a simple arithmetic sequence is 2, 4, 6, 8, ..., where 2 is the constant value between adjacent terms. The general formula for an arithmetic sequence of numbers is: a , ( a + d ) , ( a + 2 d ) , ( a + 3 d ) , ..., where a is the first term and d is the constant difference between values.

Definition: An arithmetic sequence is a sequence of the form a, a + d, a + 2d, a + 3d, a + 4d, … The number a is the first term, and d is the common difference of the. sequence. The nth term of an arithmetic sequence is given by. an = a + (n – 1)d.

Sequences are ordered lists of numbers (called "terms"), like 2,5,8. Some sequences follow a specific pattern that can be used to extend them indefinitely. For example, 2,5,8 follows the pattern "add 3," and now we can continue the sequence. Sequences can have formulas that tell us how to find any term in the sequence.

Answer: The formula for the nth term in an arithmetic sequence is an=a1+(n−1)d. This formula can be used to determine the value of any term in an arithmetic sequence.
