	OFFSET	`1,2`
	COMMENT	`As T is also the triangle of sums of consecutive distinct Fibonacci numbers, a(n) is such a sum, namely F(n+1)+F(n+2)+...+F(2n).`
	FORMULA	`a(n)=F(2n+2)-F(n+2)=T(2n-1, n), T as in A094585.`
	EXAMPLE	`a(4)=F(10)-F(6)=55-8=47.`
	CROSSREFS	`Cf. A000045, A094585.` `Sequence in context: A055552 A086750 A086749 this_sequence A140336 A055144 A052909` `Adjacent sequences: A094583 A094584 A094585 this_sequence A094587 A094588 A094589`
