Question 144249: Can some please help me?
The half life of Thorium-232 is 14 billion years. Make a table showing the half-life decay of a sample of Thorium-232 from 16 grams to 1 gram, with the time in years in the first column and the mass in grams in the second column. The sequence representing the mass of Thorium-232 is an example of the arithmetic series.
Is this true or false
THANK YOU !!!

You can put this solution on YOUR website!
it is actually a GEOMETRIC series with ratio 1/2 (HALF-life??)

start with 0 yrs and 16 g

then 14 billion yrs and 8 g

keep adding 14 billion years and dividing the grams in half until you get to 1 g
