Write an equation for the nth term of the arithmetic sequence.
2, 5, 8, 11, ...

An equation for the nth term of the arithmetic sequence.

Step-by-step explanation:

Given the sequence

2,5,8,11,...

An arithmetic sequence has a constant difference 'd' and is defined by  

here

computing the differences of all the adjacent terms

Using the nth term formula

substituting a₁ = 2, d = 3

Thus, an equation for the nth term of the arithmetic sequence.
