33 and 47
45 - 35 = 10 45 + 35 = 80
36 and 44 80/2 - 8/2 and 80/2 + 8/2
46 & 34 x+y=80 + x-y=12 2x=92 x=46 46+y=80 y=34
The sum of the first sixteen numbers of pi is 80.
It is 80*81/2 = 3240
The numbers are: -10 and -8
To find the fifth number, you can use the formula for finding the average of a set of numbers. The sum of the 5 numbers is 82 * 5 = 410. The sum of the 4 known numbers is 80 * 4 = 320. Therefore, the fifth number can be found by subtracting the sum of the 4 known numbers from the sum of all 5 numbers: 410 - 320 = 90. So, the fifth number is 90.
