2. Number Pattern Notation
Tn represents the nth term in a sequence.
Tn = 3n
For Example:
T1 =
3x1 = 3
T2 =
3x2 = 6
T3 =
3x3 = 9
End of Slide

3. Number Pattern Notation
Tn = n2
For Example:
T1 =
12 = 1
T9 =
92 = 81
T20 =
202 =
400
End of Slide

4. Number Pattern Notation
Tn = 2n
For Example:
T1 =
21 = 2
T5 =
25 = 32
T10 =
210 =
1024
