Answer
Answer is:
D=1,C=2,V=3,R=7,E=0,S=6,Q=8,P=9,T=5,U=4
Giving:
55,89,144,233,377,610,987,1597,2584,4181,6765,10946
Logic:
The brackets contain the line (from the bottom) used.
D=1 as sum of two 2-digit numbers <200 (123). C=2 by the same argument (234), therefore, because U+V doesn't carry, V=3 (345). We have V+R=E next to V+R=D=1 (456), so V+R must carry, and D=E+1, so E=0. Also V+C+1=S (456), so S=6. Q=R+D=7+1=8 (567), and the second line up tells us P=Q+1=9 (123). P+S=DT (678), so T=5, giving U=4 (123).
