Question

Consider the two patterns described below.

Pattern Rule Starting
Number
S Add 7 0
T Add 21 0

Which of the following sentences describes the relationship between the corresponding terms in the two patterns?
A.
The terms in pattern S are as large as the corresponding terms in pattern T.

B.
The terms in pattern T are as large as the corresponding terms in pattern S.

C.
The terms in pattern T are 14 less than the corresponding terms in pattern S.

D.
The terms in pattern S are 14 less than the corresponding terms in pattern T.

Answer 1

B

S's nth term = 0, 7, 14, 21, ... = 7n.
T's nth term = 0, 21, 42, 63, ... = 21n = 3·7n = 3·(S's nth term).
So each term of T is three times the corresponding term of S.
