    $\text{a}_\text{n}=\text{a}_{\text{n}-1}+\text{a}_{\text{n}-2}$
  • B
    $\text{a}_{\text{n}-1}=\text{a}_\text{n}+\text{a}_{\text{n}-2}$
  • C
    $\text{a}_{\text{n}-2}=\text{a}_\text{n}+\text{a}_{\text{n}-1}$
  • D
    $\text{a}_\text{n}=\text{a}_{\text{n}+1}+\text{a}_{\text{n}-2}$
✓

Answer

Correct option: A.
$\text{a}_\text{n}=\text{a}_{\text{n}-1}+\text{a}_{\text{n}-2}$
This is a recurrence relation which gives Fibonacci sequence.
