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

-33Because: 32 - - 33 = 65
Midway is also known as Midpoint It can be find out by: Midpoint = (54 + 76)/2 Midpoint = 65 In short 65 is the midway between 54 and 76. Thanks
11 + 6k = 65 Subtract 11 from both sides: 6k = 65-11 6k = 54 Divide by 6 to get k: k = 54/6 k = 9
65 and 2
