The next sequence for 98, 87, 76, 65 is 54 This is an arithmetic sequence with the first term being 98 and the common difference being -11 So the next term is 65+(-11) = 54
Subtract 11 each time. Easier way: Look at the numbers carefully. 98 87 76 65 54. Try to remove the seconds (the duplicates?) like this: 98 7 6 5 4. It is counting down. So, the whole pattern is: 98, 87, 76, 65, 54, 43, 32, 21, 10
Add them together. There are 15 numbers so divide the sum by 15. You can, of course, use the calculator that comes as part of your computer.
98 - 71 - 1 = 26
54 multiplied by 98 is 5,292.
The middle mber becomes the primary. Sort by that and then sort by the numbers to the left and then the numbers to the right. Example: 12-34-56 98-76-54 11-22-33 21-25-33 23-25-33 becomes: 11-22-33 21-25-33 23-25-33 12-34-56 98-76-54 Easy Schmeezy!
