Chapter  10  Additional  Review     Name:  ________________________________    For  each  sequence,  state  if  it  is  arithmetic,  geometric,  or  neither.  If  it  is  arithmetic  find  an  equation  for  the  𝑛!!  term.  If  it  is  geometric  find  the  sum  of  the  first  15  terms.  1. 1,  3,  6,  10,  15,  …            2. 40,  43,  46,  49,  52,  …            3. −4, 12,−36, 108,−324,…

For  each  sequence,  state  if  it  is  arithmetic,  geometric,  or  neither.  If  it  is  geometric  find  an  equation  for  the  𝑛!!  term.  If  it  is  arithmetic  find  the  sum  of  the  first  15  terms.  7. 1,  4,  9,  16,  25,  …            8. −34,−26,−18,−10,−2,…            9. 0,  3,  8,  15,  24,  …
