(21+53)/2 = 37
If you meant to ask what are the prime numbers between 21 and 53 inclusive, then it would be 23, 29, 31, 37, 41, 43, 47, 53
16
Do you mean like what is the number exactly between them. 53+63=116/2=58
53
37
37The answer is 37It is: 37
(21+53)/2 = 37
If you meant to ask what are the prime numbers between 21 and 53 inclusive, then it would be 23, 29, 31, 37, 41, 43, 47, 53
143 - 37 = 106 106 / 2 = 53 53 + 37 = 90 So your answer is 90. You can also add the two numbers and then divide by two to find the answer: 143 + 37 = 180 180 divided by 2 = 90
there are 12 prime numbers between 21 and 72 23, 29, 31, 37, 41, 43, 47, 49, 53, 59, 61, 67
They are: 37, 41, 43, 47 and 53

Half way between 53 and 61 is (53 + 61) ÷ 2 = 57(53 + 61) / 2 = 114/2 = 5753+61 / 2114/257 is the answer
53
The difference is 8. So add half of 8 to 53 : 53 + 4 = 57. Or subtract half of 8 from 61 : 61 - 4 = 57. Either way, the halfway point is 57.
