pattern help please??
posted by Carrie .
write the next three terms and write a rule to describe the number pattern. .57, 0.66, 0.75, .084, ...

It appears you have a typo. If so, and the last term given is 0.84, then
add .09 to get the next term, so continue with
0.93 1.02 1.11 ...
Tn = 0.48 + 0.09n 
Thank you and what does Tn mean?

the nth Term of the sequence. You may have some other notation.

Ok thanks : ) I appreciate you guys here a lot!!!!!!!
