How can we determine if a sequence is arithmetic or not

The video tutorial explains how to find the common difference in a sequence by ensuring all fractions have a common denominator. It demonstrates converting fractions, calculating differences between terms, and identifying an arithmetic sequence. The tutorial concludes with a brief introduction to a problem for practice.

Why is it important to have a common denominator when adding or subtracting fractions?

• To convert them into whole numbers

• To make the fractions look similar

• To easily add or subtract them

• To simplify the fractions

What is the equivalent of 1 when converted to a fraction with a denominator of 2?

• 2/2

• 4/2

• 1/2

• 3/2

How do you find the difference between two terms in a sequence?

• By subtracting the terms

• By adding the terms

• By dividing the terms

• By multiplying the terms

What is the result of subtracting 1/2 from 2/2?

• 0

• 3/2

• 2/2

• 1/2

What type of sequence is formed when the difference between consecutive terms is constant?

• Fibonacci sequence

• Arithmetic sequence

• Harmonic sequence

• Geometric sequence
