how to draw the graph for this problem??

Question

how many numbers of edges if the degree of sequence is 5,2,2,2,2,1.... how can we draw the graph for this problem??? there is any formula for such type of problem???

Answer 1

sum of degree = 14 = 2* edges

no of edge = 7

Answer 2

v1 has degree 5.

thereare 4 other vertices connected to v1 with degree 2 , one edge b/w each of the 2 pairs of vertices.

Then there is a vertex with degree 1 connected to v1.
