6. ### The degree sequence of a tree is (1,1,...,1,2,3,4,4,5). Determine the number of 1's in the sequence.?

... of 1s in the degree sequence. If we add up all the terms, we count every edge twice. Since this is a tree, the number of edges is v -1. Thus ( v -5)(1) + 2 + 3 + 4 + 4 + 5 = 2( v -1). Hence v = 15.
