What defines an arithmetic sequence?

• Each term differs from the next by a constant amount.

• Each term is multiplied by a constant to get the next term.

• Each term is the square of the previous term.

• Each term is divided by a constant to get the next term.

How can the nth term of an arithmetic sequence be calculated?

• By dividing the first term by the common difference raised to the power of (n-1).

• By subtracting the common difference from the first term (n-1) times.

• By adding the first term to the product of (n-1) and the common difference.

• By multiplying the first term by the common difference raised to the power of (n-1).

What formula is used to calculate the sum of the first n terms in an arithmetic sequence?

• n multiplied by the sum of the first term and the nth term, all divided by 2.

• The product of the common difference and the nth term.

• The sum of the common difference and the nth term.

• The first term raised to the power of n.

Why are arithmetic sequences considered important?

• They are the basis for all mathematical operations.

• They provide a systematic way to understand patterns and solve problems.

• They offer a method to predict stock market trends.

• They can only be used to find the sum of terms.
