1. Number Sequences

2. We all know this sequence of numbers! What is the rule?
Sequences!
We all know this sequence of numbers! What is the rule?
Of course its add one!
In today's lesson we are going to be looking at lots of different sequences!

3. What about guess the rule?
Look at these number sequences carefully can you guess the next 2 numbers?
What about guess the rule?
+10 30 40 50 60 70 80 +3 17 20 23 26 29 32 -7 48 41 34 27 20 13

4. Can you work out the missing numbers in each of these sequences?
+25 50 75
100
125
150
175
+20 30 50 70 90
110
130 -5
196
191
181
176
171
186
-10
306
296
286
276
266
256

5. Now try these sequences – think carefully and guess the last number!
+1, +2,
+3 … 1 2 4 7 11 16
double 3 6 12 24 96 48
+ 1.5
0.5 2
3.5 5
6.5 8 -3 7 4 1 -2 -5 -8

6. Try this sequence. Think carefully!
O, 0.5, 1, 1.5, 2, _____, _______, ________
What is the sequence?
What are the next three numbers?

7. The sequence is +0.5. The missing numbers are:
O, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4

8. What are the next three numbers?
Now try this one:
3, 4.5, 6, 7.5, _____, ______, _____, ____
What is the sequence?
What are the next three numbers?

9. The suequence is +1.5 So the next four numbers are:
3, 4.5, 6, 7.5, 9, , 12,

10. Fraction seqeunces!
Example:
½ , 1, 1 ½, 2, 2 ½, 3

11. Remember this sequence:
¼, ½, ¾, 1
Look at this example:
1¼, 1½, 1¾, 2, 2 ¼, 2 ½, 2 ¾, 3

12. Try these sequences: ¼, _____, ¾, _______, 1 ¼, ______.
¼, _____, ¾, _______, 1 ¼, ______.
3 ½, _____, 4, _______, 4 ½, _______.
5, 5 ¼, ______, ______, ______, _____
4. 2 ½, 2 ¾, ______, ______, _______.
