Write the Explicit Formula for the sequence 4, 2, 1, 0.5

Option A, aₙ = 4 (0.5)ⁿ⁻¹

Step-by-step explanation:

We know that the common ratio (r) is: 0.5

and first term in the sequence (a₁) is: 4

and the fact this is a geometric series, therefore the sequence would be:

=> aₙ = a₁ * (r)ⁿ⁻¹

=> aₙ = 4 (0.5)ⁿ⁻¹

Hope this helps!

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !
