I think (E) since we do not know the number of integers in the set and there is no indication that T3-T2=T4-T3 etc. (i.e. there are equal intervals between integers T1,T2...Tn)

From (1), T5 = (1/2) T4 = (1/2) 5

From (2) T5 = T1 - 15/16
==> (1/16) T1 = T1- 15/16

==> T1 = 1 and T5 = 1/6

So D

Hey guys........

I don't know the answer....I got confused b/w D and E

for stmt 2, I didn't know how to solve for T1, since T1 would be

T0+1=T0/2

and we don't know what T0 is???

anybody???

T5 = 1/2 T4 = 1/2(1/2(T3)) = 1/2(1/2(1/2T2))) = 1/2(1/2(1/2(1/2T1)))) --- per definitionof the series

which is 1/16 of T1 ..
