Question

Is the following formula recursive or explicit? *
Uo = 13
Un = Un-1 - 3
Answer plz

Recursive.

Step by step explanation:

N is the number of the term in the sequence, so Un-1 is the term previous to Un and since you’re subtracting 3 from the previous term, that means it’s recursive

Answer 2

Recursive. n is the number of the term in the sequence, so Un-1 is the term previous to Un and since you’re subtracting 3 from the previous term, that means it’s recursive
