55. a. Algebra Write the first six terms of the sequence that starts with \( 1 \) , and for which the difference between consecutive terms is first \( 2 \) , and then \( 3,4,5 \) , and \( 6 \) . 

b. Evaluate \( \frac { n ^ { 2 } + n } { 2 } \) for \( n = 1,2,3,4,5 \) , and 6. Compare the sequence you get with your answer for part (a). 

c. Examine the diagram at the right and explain how it illustrates a value of \( \frac { n ^ { 2 } + n } { 2 } \) . 

d. Draw a similar diagram to represent \( \frac { n ^ { 2 } + n } { 2 } \) for \( n = 5 \) .
