NAME

Number of n-digit entries in A070153. Number pairs (a,b)=(A070152,A070153) are such that the series a through b sums to the concatenation of a and b.

Number of n-digit terms of A070153.

DATA

2, 5, 4, 7, 10, 8, 64, 8, 1139

COMMENTS

Pairs (r,s) = (A070152(k),A070153(k)) are such that sum(j=r to s, j) equals the concatenation of r and s.

EXAMPLE

We have,for instance, the following a(3)=4 number pairs,of 3-digit greater term,exhibiting the above-mentioned property: 7+...+119=7119,78+...+403=78403,133+...533=133533,178+...+623=178623

a(3) = 4 since 119, 403, 533, 623 are the only three-digit terms of A070153.
