Be able to answer the following types of questions:

3. Write the first 6 terms of each pattern. Start at 12 each time.

b) Multiply by 3, then subtract 4

4. Find the missing number

a) 25 -  = 12                            b) 56 =  x  8              c)  + 12 = 20

d) 45 ÷  = 5                      e) 17 =  - 25              f) 18  x  = 198

g) 22 - 6 = 3 + T                    h) 5  x  6 = 3  x  Y        i)  3 + 12 = 3 x S
