# What is a Hope & Love Number™?

This is in the spirit of the What is a Word/Phrase™ series started by JLee with Number version puzzles.

If a number conforms to a special rule, I call it a Hope & Love Number™.
Use the following examples below to find the rule.

Hope & Love Numbers™ Not Hope & Love Numbers™
27 26

81 80
199 198

1490 1489
1705 1704
2509 2508
3002 3001
3900 3899

A Hope & Love number

has 5 letters in its Roman numeral representation.

Examples:

27 = XXVII, 39 = XXXIX, 81 = LXXXI, 199 = CXCIX, 230 = CCXXX, 596 = DXCVI, 954 = CMLIV, 1490 = MCDXC, 1705 = MDCCV, 2509 = MMDIX, 3002 = MMMII, 3900 = MMMCM

Counterexamples:

26 = XXVI, 38 = XXXVIII,80 = LXXX, 198 = CXCVIII, 229 = CCXXIX, 595 = DXCV, 953 = CMLIII, 1489 = MCDLXXXIX, 1704 = MDCCIV, 2508 = MMDVIII, 3001 = MMMI, 3899 = MMMDCCCXCIX

Possible title explanation (thanks Stiv!)

Romans 5's chapter title is "Peace and Hope", which is somewhat close to "Hope and Love".
Alternatively, the passage in Romans 5:5 involves both hope and love.

• Nice one +1 Re the title, rot13(V guvax lbh fubhyq ybbx hc gur puncgre urnqvat sbe Ebznaf 5 va n Ovoyr!)
