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

Write the recursive formula for the following sequence?
6, 4, 2, 0, . . .

• a_n = -2n + 8

• a₁ =6, a_n = a_n - 1 - 2

• a₁ = 6, a_n = a_n-1 + 2

• a₁ = 6, a_n = a_n-1 - 2
