4.1 Identifying terms in a sequence

Pick the BEST definition of an explicit rule

• it defines a term

• it is a function

• it is a function that allows you to find any term in a sequences without knowing previous terms

• it is a function that requires you to know the previous terms to find the next term in the sequence

find the 45th term in the sequences using the explicit rule f(n)=4n+8

• 188

• 180

• 45

• 57

find the next term using the recursive rule f(n)=f(n-1)+9 when f(1)=10

• f(2)=9

• f(2)=10

• f(2)=19

• f(2)=29

T/F:

When using a recursive rule you must know the previous term to find the next

• True

• False
