Answer 2

Answer:

We can solve this problem using sum of n terms in arithmetic progression.

The formula is :

Sum =( n/2)* (2a+(n-1d))

Here :

S stands for sum of n terms

n stands for number of terms

a stands for first term

d stands for the amount by which the series increases.

For the given problem

a = unknown , n=5 , d =5 , sum = 135

So by applying the values in above formula , we have to find the number of bugs it are initially so we get the following answer.

The bug eats 7 flies on day1 , 17 on day2 , 27 on day3 , 37 on day4 and then 47 flies on day5.

If we sum up all the numbers of flies eaten on each day we will get total number of flies.

After 3 days bug has eaten 51 flies and after day4 has eaten 88 flies .

Hope this answers your question.
