26
Edit: a₁ = 8 , a₂= 8 + 2 = 10 , a₃& a₄up by 4, a₅ & a₆ up by 8 , .... by 16
a₄= 18
a₅ = 18 + 8 = 26 => answer
The solution depends on how many numbers are missing and where they were. If there is only one, If it is between 4 and -5 then -0.5 If it is between -5 and -10 then -8 If it is between -10 and -16 then -13 Of course, the answer would be different if there were more than one number missing.
Dodging numbers may be missing numbers in a sequence. For example, the underscore in the following sequence represents such a number: 2, 4, _ , 8, 10.
The mode of a series of numbers is the value that appears most frequently. In this case, the number 8 appears three times, which is more frequent than any other number in the series. Therefore, the mode of the series of numbers 4, 4, 8, 8, 8, 10, 10, 12, 12 is 8.
380 and 410
17. The numbers are being increased by odd numbers beginning with 3.
The next two number in the series are: 5 & 16

10 (between 7 and 13)
The mode of a series of numbers is the value that appears most frequently. In this case, the number 8 appears three times, which is more frequent than any other number in the series. Therefore, the mode of the series of numbers 4, 4, 8, 8, 8, 10, 10, 12, 12 is 8.

17. The numbers are being increased by odd numbers beginning with 3.
The missing number is 34. The progressive difference between the numbers doubles: 4 + 2 = 6 6 + 4 = 10 10 + 8 = 18 18 + 16 = 34 34 + 32 = 66
To find the missing number in the sequence 10, 15, 28, we can look for a pattern in the differences between the numbers. The difference between 10 and 15 is 5, and the difference between 15 and 28 is 13. If we assume a pattern in the differences, the missing number could be 21, which fits as the average of 15 and 28. Thus, the sequence could be 10, 15, 21, 28.
12. Numbers on a clock face.
This sequence of numbers follows several different patterns. If you look at the first two numbers, 7 and 10, the difference between them is 3, which is the number that follows 10. The next two numbers, 6 and 12, are related by the number 2 because 6 times 2 is twelve. And the number that follows 6 and 12 is 2. The next two numbers are 9 and 7 which are also related by the number 2, except because 9 minus 7 is 2. Based on this, the missing number is 2.
