(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
53 is halfway between 16 and 90.You calculate this as (16 + 90) / 2.
there are 12 prime numbers between 21 and 72 23, 29, 31, 37, 41, 43, 47, 49, 53, 59, 61, 67
16
They are: 37, 41, 43, 47 and 53
Do you mean like what is the number exactly between them. 53+63=116/2=58
Half way between 53 and 61 is (53 + 61) ÷ 2 = 57(53 + 61) / 2 = 114/2 = 5753+61 / 2114/257 is the answer
53
