The pattern is 3,5,7,9. What is the 100th number in the pattern?

495

Step-by-step explanation:

3+2(100-1)

5(99)

495

219

Step-by-step explanation:

3,5,7,9 is going up by 2 so if it goes up by 2  100 times  its going to be 3,5,7,9,11,13,,15,17,19,21,23,25,27,30..218            i did this really quick in my head so it may be anumber off but im prety positive that right becuase if u look at the patter for instants the 14th number is 30 and 14*2 is 28 then u add 2 it works for all of them so i did that then i added 3,5,7,9 to it

step-by-step explanation:

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
