Introduction

Palindromic numbers are numbers which read the same from
 p_right left to right (forwards) as from the right to left (backwards) p_left
Here are a few random examples : 535, 3773, 246191642

Sums of Squares of TWO Consecutive Integers

The sequence for parameter 'A' is 2, 3, 4, 5, ... [+ 1]
The 'B' CUDApalin parameters are given by A002378 → Oblong (or promic, pronic, or heteromecic) numbers: a(n) = n*(n+1).
The 'C' CUDApalin parameters are given by A000330 → Square pyramidal numbers: a(n) = 0^2 + 1^2 + 2^2 + ... + n^2 = n*(n+1)*(2*n+1)/6.

A palindromic coincidence occurred with Five Consecutive Integers or is there a pattern ?

99 + 100 + 101 + 102 + 103 = 505
992 + 1002 + 1012 + 1022 + 1032 = 51015

10099 + 10100 + 10101 + 10102 + 10103 = 50505
100992 + 101002 + 101012 + 101022 + 101032 = 510151015

Two equations like 'number'-pregnancy. The children are the numbers 1981 and 699.
112 + 122 + 132 = 434
1198112 + 1198122 + 1198132 = 43064746034

372 + 382 + 392 = 4334
369972 + 369982 + 369992 = 4106556014

[ goto entry ]		Cher Patrick, voici les numéros 39 et 40 qui hélas ne sont pas premiers (le numéro 39 a 5 facteurs premiers mais le numéro 40 est
un semi-prime -un "vrai"- avec un facteur de 15 chiffres et un autre de 17 chiffres ):

numéro 39 :
1682059335368470748635339502861 = 29 * 109 * 35935429 * 206697457 * 71640539617
9170766967294692 + 9170766967294702

numéro 40:
3167016920841776771480296107613 = 113665666219493 * 27862564186498841
12583753257358822 + 12583753257358832

Voilà c'est tout pour les palindromes de la forme 1... ...1 ou 3... ...3 de 31 chiffres. J'ai commencé à chercher ceux de la forme 5... ...5 .
Pour espérer trouver un palprime il faut donc s'attaquer aux nombres de 33 chiffres ( vraiment dur, dur ! ). A bientôt, JCR

[ goto entry ]		Cher Patrick, voici le numéro 41 :

5450871426137276727316241780545 = 16508893703300162 + 16508893703300172

C'est le dernier des palindromes de 31 chiffres ! J'ai donc commencé la recherche des palindromes de
33 chiffres mais cela risque de prendre pas mal de temps... A bientôt. Kind regards. JCR

[ goto entry ]		Cher Patrick, ca y est ! J'ai enfin trouvé le numéro 42. Le voici :

316370934175751979157571439073613 = 125771804108820822 + 125771804108820832

mais hélas il n'est pas premier (4 facteurs ) et comme j'ai fini l'étude des palindromes de la forme 31...13 pour trouver la cinquième
solution du puzzle 14 il faudra étudier les nombres de 35 chiffres... Je ne sais pas si j'aurai le temps et le courage !
Je vais quand même essayer de finir l'étude des palindromes de 33 chiffres de la forme 5... ...5. JCR

[ goto entry ]		Cher Patrick, ... et je viens de trouver le numéro 43. Le voici:

501263304966749757947669403362105 = 158313503051184762 + 158313503051184772

Voilà, c'est tout pour aujourd'hui... J'espère arriver un jour au numéro 50 ;-) JCR

[ goto entry ]		Cher Patrick, ... avec un peu de retard voici le numéro 45 :

[ goto entry ]		Cher Patrick, Voilà dejà un an que je n'ai pas eu de tes nouvelles ( le temps passe... ) mais j'attendais de trouver le numéro 46
pour t'écrire. Ca y est ! mais hélas il n'est pas premier (petite consolation c'est un semi-prime !). Le voici :

10489844562990321812309926544898401 = 2344709 * 4473836438974014179290447789
724218356678092002 + 724218356678092012

A bientôt. JCR

A simple substitution of n with (m–1) will proof that n^2 + (n+1)^2 + (n+2)^2 equals 3*n^2 + 2 :

n^2 + (n+1)^2 + (n+2)^2 =
(m–1)^2 + ((m–1)+1)^2 + ((m–1)+2)^2 =
(m^2–2m+1) + (m^2) + (m^2+2m+1) =
m^2 + 1 + m^2 + m^2 + 1 =
3*m^2 + 2 QED
And also that n^2 + (n+1)^2 equals 2n(n–1)+1 :
n^2 + (n+1)^2 =
(m–1)^2 + ((m–1)+1)^2 =
m^2–2m+1 + m^2 =
2m^2 – 2m + 1 =
2m(m–1) + 1 QED
