It is: (28+82)/2 = 55
(28 + 82)/2 = 55
(28 + 82)/2 = 55

55. To find a number halfway between two numbers on the number line, add the two numbers together and divide by 2, so (82 + 28)/2 = 110/2 = 55. Check the answer: 55-28 = 27, and 82-55 = 27.Example: what is half way between 4 and 6 (the obvious answer is 5), but work it through: (4+6)/2 = 10/2 = 5.
The numbers between 80 and 85 are 81, 82, 83, and 84. The number that is exactly halfway between 80 and 85 is 82.5
Possibility of two digit no whose sum is 10 19,28,37,46,55,64,73,82,91 Now add 54 to each no mentioned above 73,82,91,100,109,118,127,136,145 See after 1st comma 28 and 82 Reverse of 28 is 82. That no 82 is 54 more than the no 28. So 28 is the original
Calculating the average of the two numbers gives you the answer. (Add the two numbers, then divide the result by 2.)
38 + 44 = 82/2 = 41. So -3 Halfway between two numbers is half their sum: 1/2 x (-44 + 38) = 1/2 x (-6) = -3
It is 81.5, the number halfway between the two middle numbers.
Their GCF is 2.
47 (forty-seven) 47 is 35 more than 12 and 35 less than 82 To find a halfway point (which is also the average), add the numbers together and divide by 2. 12 + 82 = 94 and 94/2 = 47
The middle number is 92
