1,3,6,10,15,21
==================================
b.Evaluate (n^2+ n) /2 for n=1,2,3,4,5 and 6.
Compare the sequence you get with your answer for part a.
If n = 1 you get (1+1)/2 = 1
If n = 2 you get (4+2)/2 = 3
If n = 3 you get (9+3)/2 = 6
etc.
===========================================================
c.Draw a diagram to represent (n squared +n)/2 for n=5.
(25+5)/2 = 15
=============================================================
