Question

Consider a sequence whose first five terms are:-1.75, -0.5, 0.75, 2, 3.25

Which explicit function (with domain all integers n ≥ 1) could be used to define and continue this sequence?

Answer 1

Explanation:

+ 1.25

every new term is the previous term + 1.25.

with starting value -1.75

f(n) = 1.25n - 1.75
