Explanation

Pattern:

18 + 12 = 30

30 + 12 = 42

42 + 12 = 54

54 + 12 = 66

Logic: Add 12 to each number.

Explanation

10, 14, 19, 28, 54, ?

Find differences:

14 - 10 = 4

19 - 14 = 5  

28 - 19 = 9

54 - 28 = 26

Differences: 4, 5, 9, 26

Look at the pattern in differences:

4 = 2^2

5 = 2^2 + 1

9 = 3^2

26 = 5^2 + 1

The next logical difference is 7^2 = 49

So next term = 54 + 49 = 103

Explanation

Check the pattern:

66 to 64 = -2

64 to 70 = +6

70 to 68 = -2

68 to ? = +6

So it alternates: -2, +6, -2, +6...

Next step after 68 should be +6

68 + 6 = 74

Explanation

Let's find the pattern in B, E, J, Q, Z, ?

Look at alphabet positions:

B = 2

E = 5

J = 10  

Q = 17

Z = 26

Now check the differences:

5 - 2 = +3

10 - 5 = +5  

17 - 10 = +7

26 - 17 = +9

The differences are +3, +5, +7, +9... odd numbers increasing by 2

Next difference should be +11

26 + 11 = 37

Alphabet wraps around after 26. So 37 - 26 = 11

11th letter = K

Explanation

Let's check the alphabet positions:

B = 2  

E = 5  

I = 9  

N = 14  

T = 20  

? = 

Differences:  

5 - 2 = +3  

9 - 5 = +4  

14 - 9 = +5  

20 - 14 = +6  

Pattern: +3, +4, +5, +6... so next should be +7

20 + 7 = 27

Alphabet wraps after 26, so 27 - 26 = 1

1st letter = A

Explanation

The pattern is: ×2 + 1

6 × 2 + 1 = 13

13 × 2 + 1 = 27

27 × 2 + 1 = 55

55 × 2 + 1 = 111

Explanation

Given sequence: 4, 11, 7, 14, 10, 17, __, 20

Two alternating series are used:

First series: 4 → 7 → 10 → 13 (+3 each time)

Second series: 11 → 14 → 17 → 20 (+3 each time)

Missing number: 13
