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:

Which term in both the patterns has the same value?
a
Term 4
b
Term 5
c
