Question

What are the first 5 terms?

Answer 1

f(n) = f(n-1) + 1.75

f(1) = -5.25

f(2) = -5.25 + 1.75 = -3.5

f(3) = -3.5 + 1.75 = -1.75

f(4) = -1.75 + 1.75 = 0

f(5) = 0 + 1.75 = 1.75

Answer: -5.25  -3.5  -1.75  0  1.75

Answer 2

f(1) = - 5,25

f(n) = f(n-1) + 1,75

f(2) = f(2-1) + 1,75

= f(1) + 1,75

= - 5,25 + 1,75

= - 3,5

f(3) = - 3,5 + 1,75 = - 1,75

f(4) = - 1,75 + 1,75 = 0

f(5) = 0 + 1,75 = 1,75

The first five terms of the sequence :

- 5,25  -3,5  -1,75  0  1,75
