FORMULA
| a(1) = 1; a(n+1), n>1 = 2*a(n) + 100. Binomial transform of [1, 101, 101, 101,...].
a(n)=101*2^(n-1) - 100. - Emeric Deutsch (deutsch(AT)duke.poly.edu), May 07 2008

EXAMPLE
| a(4) = 708 = 2*a(3) + 100 = 2*304 + 100.
a(4) = 708 = (1, 3, 3, 1) dot (1, 101, 101, 101) = (1 + 303 + 303 + 101) binomial transform of 94)
