Answer:
Step-by-step explanation:
Ellen is playing a video game in which she captures butterflies.there are 3 butterflies on screen, but the number of butterflies doubles every minute.after 4 minutes, she was able to capture 7 of the butterflies
Initial buttlerfies =3
Since doubles every minute, the no of butterflies follow a geometric progression, with first term =3, and common ratio =2
Hence in 4 minutes no of butterflies = 3(2)^(4-1) = 3(8) =24
So in 4 minutes no of butter flies =24
NO of buttlerflies captured = 7
Remaining butterflies = 17
