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

Average of numbers from 1 to 40

For consecutive numbers, average = (First + Last) / 2

= (1 + 40) / 2

= 41 / 2

= 20.5

Explanation

Pattern: Multiply by 2 and add 2.

• 3 × 2 + 2 = 8
• 8 × 2 + 2 = 18
• 18 × 2 + 2 = 38
• 38 × 2 + 2 = 78
• 78 × 2 + 2 = 158

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

For successive percentage increases you use:

Total % increase = A + B + (A × B / 100)

So: 

= 15 + 40 + (15 × 40 / 100) 

= 15 + 40 + 6 

= 61%
