Week Three Practical Problem Questions A. Determine T(n) for n = 6‚ 7‚ & 8. T(6)=(2*6*10*14)/(6-1)!=14 T(7)= (2*6*10*14*18)/(7-1)!=42 T(8)= (2*6*10*14*18*22)/(8-1)!=132 B. Do you detect a pattern to these numbers? This pattern may arise out of the numbers or the manner in which you generated triangulations. (A closed-form function for T(n) is relatively straightforward‚ but is fairly nontrivial to construct; you will not have to explore that here.) The pattern for these numbers

Self-Expression and Individualism In "A&P" by John Updike it is shown that conformism is a major part of society in that time. In the story everything is like a well-oiled machine‚ but when three girls’ walks into the "A&P" store all of this changes for Sammy.
