What is the rule of the arithmetic sequence?
Key Concepts. An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant. An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) . An explicit formula can be used to find the number of terms in a sequence.

What is the nth term in a sequence?
The ‘nth‘ term is a formula with ‘n‘ in it which enables you to find any term of a sequence without having to go up from one term to the next. ‘n‘ stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of ‘n‘.
What is an in arithmetic sequence?
An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k. Example: a1 = 25. a(n) = a(n-1) + 5.
What is sequence and example?
A sequence is a list of numbers in a certain order. Each number in a sequence is called a term . Each term in a sequence has a position (first, second, third and so on). For example, consider the sequence {5,15,25,35,…} In the sequence, each number is called a term.
How do you know if it is an arithmetic sequence?
An arithmetic sequence is a list of numbers with a definite pattern. If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence.
