Given the values of two terms of an arithmetic sequence find the first four terms

The video tutorial explains arithmetic sequences, focusing on finding the common difference and calculating terms using given formulas. It provides a step-by-step example to illustrate the process and concludes with a Q&A session.

What is the key characteristic of an arithmetic sequence?

• The sum of terms is constant

• All terms are equal

• There is a common difference between terms

• The terms form a geometric pattern

Which formula is used to find the Nth term of an arithmetic sequence?

• Nth term = First term * Common difference

• Nth term = First term + (N-1) * Common difference

• Nth term = First term / Common difference

• Nth term = First term - (N-1) * Common difference

How can you find the common difference if you have non-consecutive terms?

• Add the terms and divide by two

• Subtract the terms and divide by the number of terms minus one

• Multiply the terms and divide by two

• Subtract the terms and divide by two

If the first term of an arithmetic sequence is 2 and the common difference is 4, what is the second term?

• 4

• 8

• 6

• 10

What is the fourth term of the sequence if the first term is 2 and the common difference is 4?

• 10

• 14

• 16

• 12
