Exploring Arithmetic Sequences and Formulas

The video tutorial explains how to find terms in a sequence using a given first term and common difference. It introduces the rule for calculating terms, demonstrates finding the zero term, and applies the rule to find the 50th term in the sequence.

What is the first term of the arithmetic sequence described?

• -1

• 31

• 41

• 10

What is the common difference in the arithmetic sequence?

• 10

• 1

• -1

• 0

What value is the zero term of the sequence?

• 41

• -10

• 31

• 0

How is the nth term of the sequence calculated?

• First term * n + common difference

• n * common difference + first term

• n + common difference + first term

• First term + (n-1) * common difference

What is the 50th term of the sequence?

• 50

• 459

• -459

• 41
