, 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 DESCRIPTION
NOT, A PATTERN
1; 3; 5; 7; 9; … a) Arithmetic b) The formula for the sequence is 2n−1
pattern
2; 3; 4; 4; 6; 5; 8 … c) Not a pattern d) Irregular and unpredictable.
9; 18; 729; 6569; … e) Not a pattern f) Irregular and unpredictable.
7; 8; 10; 12; 14; … g) It is an h) The differences between terms are
alternating series increasing by 1
pattern initially, then staying constant at 2
14; 28; 34; 41; 48;... i) Not a pattern J).They're not complying with a constant patte
rn.
1.2. Complete the flow diagram below. Write only the letter and along with the
corresponding value. i.e. (f) – 34
WORKINGS ANSWERS
(a) 7 – 5 = 2 (a) 2
(b) 6 – 5 = 1 (b) 1
(c) 5 – 5 = 0 (c) 0
(d) 4 – 5 = –1 (d) –1
(e) 3 – 5 = –2 (e) –2
