Mth 163 Test Unit VI Name 1. Write the first five terms of the sequence. Assume that n begins with 1. An = -8n+36 2. Simplify the ratio of factorials. ( ) [A] 2 [B] 56 [C] 40,320 [D] 28 3. Use sigma notation to write the sum 7+10+13+16+19+22 [A] ( ) [B] ( ) [C] ( ( )) [D] ( ( )) 4. The average price of a loaf of bread n years after 1950 is approximated by the sequence an = 0.05n + 0.14. Use the sequence to predict the price of a loaf of bread in 2004. [A] $2.79 [B] $2.89 [C] $2.94 [D] $2.84 5. Determine whether the sequence is arithmetic. If it is, find the common difference. , 6. Write the first five terms of the arithmetic sequence. Find the common difference and the nth term as a function of n. a1 = 2, ak+1 = ak - 4 7. Find the partial sum [A] 10,120 [B] 9913 ( ) [C] 455 [D] 9729 8. Determine whether the sequence is geometric. If so, find the common ratio. -5,-15,-45,-135,... 9. Find the first five terms of the geometric sequence a1 =2, r = - 10. Use the Binomial Theorem to expand (2x+y)4
