The rule to get each number in a sequence is: subtract the previous number from 100, then divide the answer by 2. __,40,30,35,32.5,33.75,__

so basically \[\huge a_n=\frac{100-a_{n-1}}{2}\]

OpenStudy (anonymous):

Ummm...

OpenStudy (anonymous):

for example if we call the nth term \[\huge a_n\] and the previous one \[\huge a_{n-1}\],tp get the nth term we need to remove the previous one from hundred then divide by two ^^^^

OpenStudy (anonymous):

\[30=\frac{100-40}{2}\]
