How does the number of male and female fruit flies affect the number of flies in three weeks?

If I put one female and two males in the vial then there will be 23 adults on day 14 and 143 adults at the end of 3 weeks because on day 14 all the eggs hatch to adults.

The number fruit flies affect how many there will be in three weeks. I learned the way to tell a male from a female is to check the brissle and if its really black its a male. I also they spend 6 days as a egg and becomes  and adult in 14 days. Also that one fruit fly can lay 20 eggs. Thats what I learned from this experiment.

Step 1:Pick a combination for our flies which was female, male, male
Step 2: use fly nap to put them to sleep
Step 3:put food into vial for flies to eat
Step 4:put combination on vial for flys and seperate them
step 5:put the flies in and put a stopper in it
Step 6:make weekly observations of the vial and two other groups vial
Step:use fly nap to make them fall asleep and count them

My data did not support my hypothesis because there was not 143 adults at the end of the experiment it may have been because I overestimated how many babies would be produced or how many adults would hatch.

Therefore I my hypothesis wrong and there was only 108 adult flies on day 14 and not 143 like I predicted.
