Question

A huge frog ate 140 Big bugs in 5 days. Each day, it ate 8 more bugs than it did on the previous day.How many bugs did the frog eat on

The first day…

The fifth day…

Answer 1

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
