Respuesta :
Let a = the number of candies eaten on the first day.
Because the number of candies eaten decreases by 6 every day after, the number of candies eaten creates the arithmetic sequence
a, a-6, a-12, a-18, ...,
After 5 days, the total candies eaten is 5a - 60.
Therefore
5a - 60 = 100
5a = 160
a = 32
On the third day, the number of candies eaten is
a - 12 = 32 - 12 = 20
Answer: 20
