Write both an explicit equation and a recursive equation for the sequence 4, 2, 1.0.5.0.25 help pleasee​

Step-by-step explanation:

This is a geometric sequence with  first term a1 = 2 and common ratio r = 0.5.

an = a1 r^^n-1)

an = 2(0.5)^(n-1).

Recursive equation:

an = 0.5a(n-1) where n > 2

idk

step-by-step explanation:

your victory is right around the corner. never give up.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
