Question

Each year, a daylily farm sells a portion of their daylilies and allows a portion to grow and divide. The recursive formula

Answer 1

Answer:

  600

Step-by-step explanation:

We can solve the recursive formula for the previous term in terms of the present one:

  a[n-1] = (a[n] +100)/1.5

Working backward, we find ...

  a[4] = (a[5] +100)/1.5 = (2225 +100)/1.5 = 1550

  a[3] = (1550 +100)/1.5 = 1100

  a[2] = (1100 +100)/1.5 = 800

  a[1] = (800 +100)/1.5 = 600

There were 600 daylilies on the farm after the first year.
