First digit is three times fifth one 2*3=6
Third digit is three less than second 5-3=2
Fourth digit is four more than second 5+4 = 9
Three pairs of digits sum up to 11 --? 6,5 / 2,9 / 9,2

5digit number = abcde
a=3e ; three pairs (of ab,bc,cd,de) sum up to 11 ---> conclusion: b,c,d > 1 and 0 < e < 4
d= b+4 and c= b-3 ---> d- c = 7
if d=8 then c=1 (wrong because c >1); so d = 9 and c=2 ----> b=5
bc pair sum up to 5+2=7 so other three pairs sum up must be 11
so a=11-5=6 and e=11-9=2 or e=6/3=2
Hence five digit number is: 65292
