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.
169
98 - 27 = 71
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!

We could be here a while! multiples of 27 are numbers 27 divides INTO, therefore, 27 is the first, then 54, 71, 98, 125, 152...... there are an infinite number of multiples.
It is: 98/108 = 49/54
