Question

62,57,52,47,42 recursive formula

Answer 1

1st sequence: f(n)=f(n-1)-5 with f(1)=62.

2nd sequence: f(n)=f(n-1)+9 with f(1)=-15.

Explanation:

The first sequence, to get the next term you just subtract 5 from the previous term.

The recursive form is f(n)=f(n-1)-5 with f(1)=62.

The sequence, to get the next term you just add 9 to the previous term.

The recursive form is f(n)=f(n-1)+9 with f(1)=-15.
