Sequences and Series Assignment Write the first 5 terms of the sequence. (Assume n begins with 1.) 1) an = 2n +5 1+(-1)" 4) an = n 2) an = (-2)n Find the indicated term of the sequence. 5) an = n n+1' a10 = 6) an =(-1)-1[n(n-1)]; a16 = n 3) an = n+1 Write an expression for the apparent nth term of the sequence. (Assume n begins with 1.) 7) 1, 4, 7, 10, 13, ... 1 1 1 8) 1, , 4 16' 25'' 9) -1 4 ... 16 Write the first 5 terms of the sequence defined recursively. 10) a = 15, ak+1= ak +3 11) a = 15, a k+1=ak +3 12) a = 25, ak+1 = ak- Simplify the factorial expression. 13) 4! Find the Sum. 14) 10! * 3! 4!* 6! 15). 12! 4!* 8! 16) (2i+1) 17) =14 18) -0(312)
