simply write “yes” or “no” next to each statement. Add consecutive odd numbers: 11 (a) Increase the difference between consecutive terms by 2 then 15 and so on each time (c) 4; 14; 29; 49; 74; 104; 139; Yes. 179 Test: The difference between 17 and 10 is 7. Add consecutive multiplies of 5: If I increase the difference by 2 I get 9 10 then 15 then 20 and so on To get the next term , I add 9 to 17 to get 26 (d) 5; 6; 8; 11; 15; 20;26; 33; 41 I continue this way of reasoning to get the other terms Add consecutive natural numbers: 1 then 2 then 3 and so (b) Increase the difference between consecutive terms by 1 on each time No. Test: The difference between 17 and 10 is 7 If I increase the difference by 1 I get 8 To get the next term I add 8 and 17 It gives me 25 which is not the next term in the sequence (c) Add two more than you added to get the previous term Yes. Test: The difference between 17 and 10 is 7. If I increase the difference by 2 I get 9 To get the next term , I add 9 to 17 to get 26 I continue this way of reasoning to get the other terms SUBJECT: MATHEMATICS GRADE 8 - Term 1 WEEK 6 LESSON 4 TOPIC: Patterns, functions and algebra - Functions and relationships
