Posted by Kl on Wednesday, March 4, 2009 at 8:39pm.
For what values of t will t-2, 2t-6, and 4t-8, in this order, form an arithmetic sequence?
Could someone at least start me off?

There is an arithmetic progression if
2t-6 -(t-2) = (4t-8)-(2t-6)
t -4 = 2t -2
t = -2
in which case the sequence is -4, -10, -16
