9. Count the number of patio stones for the flower beds below and generalise your results. n = 1 n = 2 n = 3 Number of patio stones =10 Number =17 Number =24

10. n = 4 n = 5 n = Number of patio stones =31 Number of patio stones = 38 28 Number of patio stones = 199 Count the number of patio stones for the flower beds below and generalise your results.

11. We can summarise our results in a table From this we can identify a general rule n1234528 Patio Stones1017243138199 Patio stones = 3 + 7n

14. The 7 th,8 th and 9 th terms of a sequence are 61, 69 and 77. Find the formula to describe this sequence. Hence find the 100 th term. Find the differences So the sequence is of the form ? ? ? ? ? ?

15. Find the differences So We find b by using ? ? ? ? ? ? ? ?
