Answer:
66 feet
Step-by-step explanation:
The space between the first two crops is 3 feet, between the first and the third is 6 feet, between the first and the fourth is 9 feet hence, the relationship between the first and the nth crop is given by
3(n - 1)
As such, if there are 23 crops, the distance between the first and last plant
= 3(23 - 1)
= 3(22)
= 66 feet
