∙ 6y agoHalfway between 42 and 82 is (42 + 82) ÷ 2 = 124 ÷ 2 = 62.
82 + 102 = 64 + 100 = 164

9 with remainder 82.
== 49 == 144 = 122 121 = 112 100 = 102 81 = 92 64 = 82 Implies 122, 112, 102, 92, 82 So the next number should be 72 = 49. So, the next number is 49.

No, 82 is not a multiple of 9 because 9 can not be multiplied by any whole number to get 82. (9x9=81, 9x10=90, there is no 82 in between).

All multiples of 5 end in 0 or 5. So, the only number between 102 and 108 which is a multiple of 5 is 105.
It is 88, the number halfway between them.
List the numbers in order (on paper) , for example: 2, 5, 23, 67, 71, 82, 99, 102. Start at the numbers 2 and 102. Have both fingers on them. Let the finger on 2 move to 5, the finger on 102 move to 99. Continue on and have the finger on 5 move to 23 and the finger on 99 move to 82. Do that step one more time and have the finger on 23 move to 67 and the finger on 82 move to 71. Usually, there's a number in between and that would be your median. In this case, there is no middle number. So you would take a look at 67 and 71 and think 'What are the numbers between 67 and 71?'. 68, 69,70. This part is really easy, because 69 is in the middle, so that is your median!
It is: (28+82)/2 = 55(28 + 82)/2 = 55
