Which answer describes the pattern in this sequence?

2,1,1/2,1/4

1/8 :)

Step-by-step explanation: This pattern is dividing each previous number by two. 1 is half of 2, 1/2 is half of 1, 1/4 is half of 1/2, and 1/8 is half of 1/4.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
