You may have already looked at how to write a rule to describe number patterns. Now we are going to extend this and learn how to write general rules using pronumerals.
A pronumeral is a letter mathematicians use to represent an unknown value. Watch this value to see how we can use pronumeral to describe patterns with fractions.
Complete the following pattern.
$0.01$0.01 | $0.02$0.02 | $0.03$0.03 | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
If $c$c belongs to the same pattern, what is the next number?
Complete the following pattern.
$0.15$0.15 | $0.14$0.14 | $0.13$0.13 | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
If $x$x belongs to the same pattern, what is the next number?
Consider the following pattern.
What is the pattern?
$0.03$0.03 | $0.11$0.11 | $0.19$0.19 | $\editable{}$ | $\editable{}$ | $\editable{}$ |
The numbers are increasing by $0.08$0.08.
The numbers are increasing by $80$80.
The numbers are increasing by $8$8.
The numbers are increasing by $0.8$0.8.
Now complete the pattern.
$0.03$0.03 | $0.11$0.11 | $0.19$0.19 | $\editable{}$ | $\editable{}$ | $\editable{}$ |
If $x$x belongs to the same pattern, what is the next number?
