Each year, a daylily farm sells a portion of their daylilies and allows a portion to grow and divide. The recursive formula an = 1.5(2n-1)-100
represents the number of daylilies, a, on the farm after n years. After the fifth year, the farmers estimate
they have 2,225 daylilies. How many daylilies were on the farm after the first year?

  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.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
