The digits must satisfy the two conditions.
Each digit consists of a different one from 0, 1, …, 8, 9 in a pair of 10 numbers.
Every ten digits are equal.
\large\underline{\large\underline{\text{Explanation}}}
Explanation
Let's find the sum of a pair consisting of 10 different digits.
\cdots\longrightarrow0+1+\cdots+8+9=\dfrac{1}{2}\times10\times9⋯⟶0+1+⋯+8+9=
2
1
×10×9
\cdots\longrightarrow0+1+\cdots+8+9=45.⋯⟶0+1+⋯+8+9=45.
Every ten digits repeat 11 times, so the sum is,
\cdots\longrightarrow45\times11=495.⋯⟶45×11=495.
So, the answer is,
\cdots\longrightarrow\boxed{495.}⋯⟶
495.

Where a,d,la,d,l are the first term, common difference, last term, the arithmetic terms are,
\cdots\longrightarrow a,a+d,a+2d,\cdots,l-2d,l-d,l⋯⟶a,a+d,a+2d,⋯,l−2d,l−d,l
Let S_{n}S
