Answer = 64
ANSWER: The next prime number after 80 is 83.
75.
For instance, all the even numbers greater than 70 are composite.The next few composite numbers greater than 70 are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, ...
2 x 37 = 74 As the product is an even number one of the prime numbers must be 2. Then just check all the even numbers between 70 and 80 that is double a prime number: 74 = 2 x 37.
The composite numbers between 70 and 80 are 72, 74, 75, 76, 77 and 78.

if x + 74% of x = 80 then: 100% of x + 74% of x = 174% of x = 80 → x = 80 ÷ 174% = 80 ÷ 174/100 = 45 85/87 ≈ 45.977
ANSWER: The next prime number after 80 is 83.
74/100 * 80 = 59.2
70, 72, 74, 75, 76, 77, 78, 80
After putting them in order, cross out the 'ends' First 58 and 80 Then 58 and 74 You are left with 63 and 69 The median number is 66. The median is the number in the 'middle.'
-57The first two numbers in the series has a difference of 89. The next two numbers (209, 129) has a difference of 80. The next two (129,58) has a difference of 71. As you can see the differences change by 9, so the next two numbers in the series (58, -4) has a difference of 62. Following this pattern, the next two numbers in the series will have a difference of 53. So the next number in this series will be (-4-53 = -57).
Each number is multiplied by negative 2 to get the next number. 5 x -2 = -10 -10 x -2 = 20 20 x -2 = -40 -40x -2 = 80 So the next logical number in the series 5 10 20 -40 would be 80.
