Question

A sequence is defined by the recursive formula f(n+1)=1.5(n). Which sequence could be generated using using the formula ?

Answer 1

The sequence rule is f(n+1)=1.5(n), then

for n=0, f(1)=0;
for n=1, f(2)=1.5;
for n=2, f(3)=3;
for n=3, f(4)=4.5, and so on.
You receive the arithmetic sequence 0,1.5,3,4.5,....
