Question

The sum of five consecutive even
numbers is equal to 170. What is the sum
of the second largest number amongst
them and the square of the smallest
number amongst them together?​

Answer 1

Answer:

936

Step-by-step explanation:

let the five consecutive even numbers are :

x, x+2, x+4, x+6, x+8                

(we added two here because the difference between two even numbers is 2)

According to the question

x+x+2+x+4+x+6+x+8 = 170

5x+20 = 170

5x = 150

x = 30

Hence the numbers are

30, 32, 34, 36, 38

Now, here the second largest number is 36

and, smallest number is 30

Now according to question

$30^{2}+36\\= 936$

That's the answer.
