Question 1
1.1. Copy and complete the table below by describing how you decided whether the set of
number sets in the preceding column is a pattern or not:
Number set Pattern or not, a pattern Description
1; 3; 5; 7; 9; … a) Yes b) It increases by 2 each time (odd numbers).
2; 3; 4; 4; 6; 5; 8 … c) No d) There is no consistent rule or sequence.
9; 18; 729; 6569; … e) No f) No logical or mathematical pattern is clear.
7; 8; 10; 12; 14; … g) Yes h) Starts at 7, then increases by 1, 2, 2, 2.
14; 28; 34; 41; 48; … i) Yes j) +14, +6, +7, +7 — not simple but a pattern
forms.
1.2. Complete the flow diagram below. Write only the letter and along with the corresponding
value. i.e. (f) - 34
To complete the flow diagram, subtract 5 from each input value:
7−5=2
6−5=1
5−5=0
4 − 5 = -1
3 − 5 = -2
Now match each result with a letter:
(a) – 2
(b) – 1
(c) – 0
(d) – -1
(e) – -2
