I need to know the pattern. I wasn't at school when the teacher taught the information.
3, 3.3, 3.63, 3.993
What's the pattern? I need help.

Add 10% to each number before. Or multiply by 1.1

Look at the ratio between successive terms
t(2)/t(1) = 3.3/3 = 1.1
t(3)/t(2) = 3.63/3.3 = 1.1
t(4)/t(3) = 3.993/3.63 = 1.1
This is sequence is what's called a geometric sequence ( or progression ) and 1.1 is what's called the common ratio.
Any term n in the sequence can calculated explicity by
t(n)=3*(1.1)^(n-1)
or implicitly by multiplying the previous term by 1.1
t(n) =1.1*t(n-1)

You are multipying each one by 1.1 to get the next one.
