Double, Double, Plus 1/4
Next three: 50, 100, 125
4, 20, 25
To find the mean of the numbers 10, 20, 25, and 15, first add them together: 10 + 20 + 25 + 15 = 70. Then, divide the total by the number of values, which is 4. So, the mean is 70 ÷ 4 = 17.5.
5, 10, 15, 20, 25, etc.
The next number is 30. The numbers are increasing in multiples of 5.
20 + 25 = 45
-10
The Next NumberThe next number is 25 if you use the following pattern: 5, (the number 10), 15 (the first number +10), (the number 10), and the next number is the third number +10 or 25.or you could think of it this way:5, 10 (+5), 15 (+5), -5 (10)The pattern is +5, +5, -5, so the next number would be 15, the next 20, and the next 15.
23
no 5 is not a composite number 10 15 20 and 25 are composite
10, 20 and 25
Ni = N(i-1) - 5
4, 20, 25
To complete the sequence 5, 10, 3, 15, 20, 13, 25, 30, we can look for patterns. The first set of numbers (5, 10, 15, 20, 25, 30) increases by 5, while the second set (3, 13) appears to increase by 10. The next logical number in the pattern would be 35, following the sequence of increasing by 5. However, if we are looking for a continuation of the second set, the next number would be 23 (13 + 10).
107.5
To find the mean of the numbers 10, 20, 25, and 15, first add them together: 10 + 20 + 25 + 15 = 70. Then, divide the total by the number of values, which is 4. So, the mean is 70 ÷ 4 = 17.5.
