write each sum using summation notation.
Q1) 2 + 5 + 8 + 11 + ... + 29
Q2) 6 - 12 + 24 - 48 + ...

find the first 4 terms and the 8th term of the recursively-defined sequence.
Q1) c1 = 2, c2 = -1, and ck+2 = ck + ck+1 for k>0

Hi,

General Summation Notation : 

{2 + 5 + 8 + 11 + ... + 29} Arithemetic, d = 3 

   



{6 - 12 + 24 - 48 + ...}  Geometric, r = (-2)  





 = 2, = -1, and c[k+2] =  + c[k+1] for k>0 

 { 2, -1, 1, 0, 1, 1, 2, 3 }  previous two terms added to get the next
