  • 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
