What is the explicit formula for the nth term of the given sequence?

• A(n) = 9 + 7(n - 1)

• A(n) = 7 + 9(n - 1)

What is the explicit formula for the nth term of the given sequence?

• A(n) = 5 + 4(n - 1)

• A(n) = 5 + -4(n - 1)

A number sequence formed by adding a fixed number to

each previous term to find the next term. The fixed number is called the common difference
