Question

Miriam has a bamboo plant that is 20 centimeters tall. The plant grows at a rate of 2 centimeters a week. Which recursive formula gives the plant’s height at any week in the future? next = 20 × now + 12, starting at 12 next = now + 2, starting at 20 next = now + 20, starting at 2 next = now + 20, starting at 12 next = 12 × now + 20, starting at 20

Answer 1

now=20+2(prevous week)


next=2+now
starting at 20


2nd option
vey confusing notation
easier is
f(n+1)=2+f(n) and f(1)=20
