Algebra | The nth Term | Maths with Mrs. B

The video tutorial explains how to find the NTH term expression for arithmetic sequences. It begins with an introduction to sequences and the concept of the NTH term. The tutorial then demonstrates how to derive the NTH term expression by identifying the common difference and the term before the first term. Several examples are provided to illustrate the process for different sequences. The video concludes with a challenge for viewers to find the NTH term and the 50th term of a given sequence.

What is the purpose of the NTH term expression in a sequence?

• To identify the first term of the sequence

• To determine any term in the sequence

• To find the sum of all terms in a sequence

• To calculate the average of the sequence

In the sequence 5, 8, 11, 14, what is the common difference?

• 2

• 3

• 4

• 5

How do you find the term that comes before the first term in a sequence?

• Divide the first term by the common difference

• Multiply the first term by the common difference

• Subtract the common difference from the first term

• Add the common difference to the first term

What is the NTH term expression for the sequence 30, 40, 50, 60?

• 10N - 20

• 10N + 30

• 10N - 10

• 10N + 20

For the sequence 1, 3, 5, 7, what is the NTH term expression?

• 2N - 1

• 2N + 1

• N - 2

• N + 2

In the sequence -4, -7, -10, -13, what is the common difference?

• -3

• -5

• -4

• -2

What is the NTH term expression for the sequence -6, -4, -2, 0?

• 2N - 6

• 2N + 8

• 2N - 8

• 2N + 6
