Arithmetic Sequence Recursive

Write the recursive formula for 6, 17, 28, 39, 50....

• a_n=a_n-1+11
  a₁=6

• a_n=a_n-1-4
  a₁=6

• a_n=a_n-1+9
  a₁=6

• a_n=a_n-1+6
  a₁=6

Given the recursive formula, find the first four terms:
a_n = a_n-1 + 5
a₁ = -16

• -16, -21, -26, -31

• 5, -11, -27, -43

• -16, -80, -500, -200

• -16, -11, -6, -1

Find the 4th term for the sequence defined by a₁=9; a_n=a_n-1+8

• 35

• 17

• 41

• 33

Identify the rule as recursive or explicit, then find the first 4 terms of the sequence.
a₁ = 100; a_n = a_n-1 - 8

• Explicit; 100, 92, 84, 76

• Recursive; 100, 92, 84, 76

• Explicit; 100, 108, 116, 124

• Recursive; 100, 108, 116, 124

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

• 1

• 2

• 4

Find the 32nd term of this sequence.
34, 37, 40, 43, ...

• 32

• 64

• 127

• 356

Which of the following recursive formulas represents the given sequence.

Write a recursive rule for the arithmetic sequence 17, 1, -15, -31 . . .

• a_n = a_n-1 + 16
  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 are the next 3 terms in this sequence of terms? 3, 7, 11, 15

• 18, 22, 26

• 19, 21, 23

• 19, 23, 27

• 18, 21, 24
