Easy arithmetic problem:
[tex]x=222,222,222,222,222,222,222^2-222,222,222,222,222,222,221^2[/tex]
Find x.
[tex]x=222,222,222,222,222,222,222^2-222,222,222,222,222,222,221^2[/tex]
Find x.
kevinferreira said:[tex] x=(n+1)^2-n^2=2n+1 [/tex]
where [itex] n=222,222,222,222,222,222,221 [/itex].
Therefore
[tex] x=444,444,444,444,444,444,443 [/tex]
