Two sequences $A=\{a_0, a_1, a_2,\ldots\}$ and $B=\{b_0,b_1,b_2,\ldots\}$ are defined as follows:\[a_0=0, ~a_1=1, ~a_n= a_{n-1} +b_{n-2} \hspace{2mm}\text{for}\hspace{2mm} n\ge2\]\[b_0=1, ~b_1=2, ~b_n=a_{n-2} +b_{n-1}\hspace{2mm}\text{for}\hspa ce{2mm} n\ge2\]What is the remainder when $a_{50}+b_{50}$ is divided by $5$?

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
