The sum of five consecutive integers is 75. What is the third number?

Answers

Answer 1

Answer:

Hi,

Let us assume those 5 integers are:

a-2, a-1, a, a+1, and a+2.

I have intentionally chosen the numbers this way to have a simple and useful sum of them, see below.

Their sum is: a-2 + a-1 + a + a+1 + a+2 = 5a = 75, therefore a = 15, which is exactly the 3rd number.

Oliver buys yen stamps each costing 77centscomplete the calculation he could do to find the total cost

Answers

Hi!
I think that you misspelled the question, and you mean that Oliver bought "ten", not "yen" stamps- yen is the currency of Japan.

So we have 10 stamps of 77 cents each:

10*77=770 cents

He has to pay 770 cents, or since 100 cents are one dollar, 7 dollars and 70 cents.

The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?

Answers

A simple way to solve for consecutive numbers is to divide the sum number by the number of numbers needed. So 310 ÷ 5, which equals 62. That is the middle consecutive number.

To find the other 4 numbers, since they are all even, sinply add 2 to the middle number to find one, add 2 to that to find another, subtract 2 from the middle number to fine the third, and subtract 2 from that to find the final one.

62 + 2 = 64
64 + 2 = 66
62 - 2 = 60
60 - 2 = 58

so your numbers are 58, 60, 62, 52, and 66. Together they add up to 310.

(I may have done this a non-standard way, bit it was the way that made the most sense in my head.)
