    I think the average decrease was 2, as it started with 15 and after 5 years decreased by 10 thus, 10 divided by 5 is 2

    No it's 2.5, I worked it out in my head

    15, 12.5, 10, 7.5, 5 (5 years)
    15, 13, 11, 9, 7, 5 (6 years)

    Edit: wait, I see what you mean, I don't think I'm right

    I think it was why the rat something plant decreased, it was after calculating the average decrease of the plant

    I got 2.5 as I worked out the mean (x̄=∑x/n) which was 10/4. I got 4 as it decreased 4 times over 5 years - if it was 5 times then it would be 6 years.

    10/4 = 2.5

    Same, that question was quite tricky though, I had to use the knowledge of the radioactive decrease of a radioisotope to get that from chem and physics ( don't ask me why lol).
