52+54+56 = 162
(51+57)/2 = 54
The integers are 51, 53, 55 and 57.
Half of 51/57 = 51/(57*2) = 51/114 = 0.4474 approx.
The sum of the numbers between 51 and 150 is equal to 10050 - or 50 x 201 - as there are 50 lots of 201 in the sum.
51 54 57
The numbers are 51, 53, 55 and 57.
Oh, dude, you're really testing my math skills here. Let me grab my calculator... just kidding. The sum of the prime numbers between 51 and 69 is 53 + 59 + 61 + 67, which equals 240. So, like, if you were wondering if you could impress your friends with this fact at a party, you totally can.
Let the lowest odd number equal x, thus: x + x + 2 + x + 4 = 57 3x + 6 = 57 3x = 57 - 6 3x = 51 x = 51/3 x = 17 The three numbers are therefore 17, 19 and 21.
57.
The odd numbers between these values are 49, 51, 53, 55, 57 and 59.
