Consider the following sequence.

$2,-1,1,0,1,1,\text{. . .}$2,−1,1,0,1,1,. . .

Consider the following sequence.

$\pi,\pi,2\pi,3\pi,5\pi,8\pi,\text{. . .}$π,π,2π,3π,5π,8π,. . .

Use the fact that the Fibonacci sequence is defined by $t_n=t_{n-2}+t_{n-1}$`t``n`=`t``n`−2+`t``n`−1, where $t_1=1$`t`1=1 and $t_2=1$`t`2=1, to generate terms $3$3 to $8$8.

Write all the values on the same line, separated by commas.
