14 numbers are written in a row so that the sum of any three consecutive numbers is
19, and the sum of all the numbers is 77. Find the 9th number.

Respuesta :

The series of numbers that meets the requirements is 5+6+8+9+4+6+7+3+9+2+8+9+1.

How to check that the series meets the requirements?

To verify that the series meets the requirements, we must establish what the requirements are:

  • Every 3 consecutive numbers must add up to 19.
  • In total there must be 14 numbers.
  • The total sum of all the numbers must be 77.

To verify that every 3 consecutive numbers add up to 19, we separate them into 4 groups of 3 and one number is left over.

  • 5 + 6 + 8 = 19
  • 9 + 4 + 6 = 19
  • 7 + 3 + 9 = 19
  • 2 + 8 + 9 = 19

In total there must be 14 numbers and they must add up to 77.

5+6+8+9+4+6+7+3+9+2+8+9+1 = 77
