a) Draw a tree with n vertices with n+1 vertices of degree 2, n+2 vertices of degree 3, and n+3 vertices of degree 1. Where n is even digit of your arid number e.g 19-arid-738 take n=7 (b) For the given sequence 1/n, 1/2n, 1/4n. Find the 16th term. Find sum of first sixteen terms where n is your arid number i.e. 19-arid-738 take n-738 (c) Find the Graph whose adjacency matrices is given by 0100|0 0 10 1010 0 10 1 1 0 0 010| 10 0111 0 1 0|0|0|0| 10 How many walks of length 2 are there from v2 to v3?
