The answer is 65292
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

There is a combination lock with four inputs 0-9. Can you figure it out?

The second isn't a 6.

Only one digit starts with a vowel.

The fourth is greater than the first, is greater than or equal to the third, and is greater than the second.

Either the first two numbers are even & the last two numbers are odd or vice versa.

The difference between the 1st & 2nd is the same as the difference between the 4th & 3rd (order matters).

One of the numbers is prime; three are composite.
