T(n+1)=T(n)+1/2 , T(1)=3 ←係唔係這樣意思?
T(2) = T(1) + 1/2
. = 3 + 1/2
. = 3.5
T(3) = T(2) + 1/2
. = 3.5 + 1/2
. = 4
T(4) = T(3) + 1/2
. = 4 + 1/2
. = 4.5
T(5) = T(4) + 1/2
. = 4.5 + 1/2
. = 5
Therefore:
T(1) = 3
T(2) = 3.5
T(3) = 4
T(4) = 4.5
T(5) = 5
T(2) = T(1) + 1/2
. = 3 + 1/2
. = 3.5
T(3) = T(2) + 1/2
. = 3.5 + 1/2
. = 4
T(4) = T(3) + 1/2
. = 4 + 1/2
. = 4.5
T(5) = T(4) + 1/2
. = 4.5 + 1/2
. = 5
Therefore:
T(1) = 3
T(2) = 3.5
T(3) = 4
T(4) = 4.5
T(5) = 5
