The nth term of AP (Arithmetic Progression) is used to find any term of it. Usually, a term of AP is obtained by adding the common difference of AP to its previous term. But using the nth term of AP formula, we

Sometimes the arithmetic sequence is also named arithmetic progression. An arithmetic sequence is also defined as each term of the sequence, except the first term is obtained by adding a fixed number to its previous term. How do you solve an arithmetic sequence? An arithmetic sequence is solved...

The explicit formula for an arithmetic progression has the form "a(n) = a(1) + n*r," in which "a(n)" is the nth term (defined as any term in the arithmetic sequence) of the progression, "a(1)" is the first term, and "r" is the common difference. This formula can be easil...
If in a sequence the difference between any two consecutive terms remains constant, then the sequence is said to be in arithmetic progression. For example, a,a+d,a+2d,a+3d,⋯ is an arithmetic sequence and in this sequence, a is the first term an...
