To find the halfway point: (27 + 43) ÷ 2 = 35
35(27+43)/2 = 70/2 = 35 ■
13 ...23 ...33 ...43 ...53=125■
43 minus the sum of 16 and 11 can be calculated as follows: 16 + 11 = 27 43 - 27 = 16 Therefore, 43 minus the sum of 16 and 11 is equal to 16.

43
It is 55, the number halfway between them.
It is 26, the number halfway between them.
35
1/2(64+22) = 43
43 (the other 3 are divisible by 3)
26 It is 17 more than 9 and 17 less than 43. To find a halfway point (which is also the average), add the numbers together and divide by 2. 9 + 43 = 52, and 52/2 = 26
x+27=43 x+27-27=43-27 x+0=16
They are all composite numbers except 43 which is a prime number
