Question

1 Look at the following rules for two number patterns. Both patterns start with 40.

Pattern P: "Subtract 2"

Pattern Q: "Subtract 6"


Which statement is true about the corresponding terms in the two patterns?


a

Excluding the first term, a term in Pattern P is always 4 greater than its corresponding term in Pattern Q.


b

Excluding the first term, a term in Pattern Q is always 6 greater than its corresponding term in Pattern P.


c

Starting with 0, the difference between the corresponding terms in the two patterns decreases by 2.


d

Starting with 0, the difference between the corresponding terms in the two patterns increases by 4.


2 The following rules for two patterns are shown:

Pattern A: "Start at 100, subtract 10"
Pattern B: "Start at 75, subtract 5"

Which term in both the patterns has the same value?

a
Term 4

b
Term 5

c
Term 6

d
Term 7
