  a₁=17

• a_n = a_n-1 - 17
  a₁=17

• a_n = a_n-1 - 15
  a₁=17

• a_n = a_n-1 - 16
  a₁=17

What is the recursive formula for arithmetic sequences?

• f(n) = f(n-1) + d

• f(n) = f(1) + (n+1)d

• f(n) = f(1) + nd

• f(n) = f(1)+ (n-2)d

Given      t(n+1) = t(n) - 3 
and          t(1) = 6,
is this sequence also arithmetic or geometric or neither?

• arithmetic

• geometric

• neither

• Pick this one...if you like getting answers wrong
