Yes they are equivalent.The reason is if you expand them and simply them you will get the answer of 3x+5y+10.
The first two (top two) choices should be selected. The midpoint of a line segment divides the line segment into two congruent parts, so the first is true by the definition of midpoint. The whole is the sum of its parts; Adding the two smaller segments will always equal the whole.
Explanation
Given that Sn = Sn-2 . (Sn-1 - 1)
Tn = Sn - Sn-1
Tn = Sn-2 . (Sn-1 - 1) - (Sn-3 . (Sn-2 - 1))
T3 = S1.(S2-1) - (S0.(S1-1)
T3 = 2.(3-1) - 1.(2-1)
T3 = 2(2) - 1(1)
T3 = 4-2
T3 = 3
T4 = S2.(S3-1) - (S1.(S2-1)
T4 =3.(-1) - 1.(2-1)
T4 = 2(2) - 1(1)
T4 = 4-2
T4 = 3
