Chiaki is interested in an infinite sequence a1, a2, a3, ..., which defined as follows:
%5E%7B%5Cfrac%7Bn(n%2B1)%7D%7B2%7D%7D%20%26%20n%20%5Cge%202%5Cend%7Bcases%7D)
Chiaki would like to know the sum of the first n terms of the sequence, i.e.
. As this number may be very large, Chiaki is only interested in its remainder modulo (109 + 7).
Chiaki would like to know the sum of the first n terms of the sequence, i.e.
