Answer:
on the first day, the frog ate 12 bugs and on the fifth day it ate 44 bugs
Step-by-step explanation:
a=?
n=5
Sn=140
d=8
Sn= n/2 (2a + (n-1)d)
140= 5/2 (2a +32)
140 = 5 (a+16)
28 = a+16
a= 12
so on the first day it ate 12 bugs
now let`s find the fifth day
a= 12
d=8
n=5
a5 = ?
a5= a+ 4d
a5 = 12 +4(8)
a5 = 44
therefore, the frog ate 44 bugs on the fifth day
hope my answer helped you
