**HELP HELP HELP MNHS**, Sunday, February 3, 2013 at 4:43pmwe can get CD by getting the CR using geometric sequence since the common ratio (CR) & common diff (CD)are the same... so,

A sub 6=A sub 1 r^(n-1)

96=3r^5

r^5=32

r=2-------> CD is also 2

THEN,

the first 5 terms of an arithmetic sequence using CD of 2 are:

3, 5, 7, 9, 11
