Explanation

 OX, QZ, SX, UZ

the logic is:
after "O", "P" is missing, and the next Letter is "Q"

after "Q", "R" is missing, and the next Letter is "S"

after "S", "T" is missing, and the next Letter is "U"

Explanation

What is the missing number in the sequence? 1, 1, 2, 3, 5, 8, ?

1 + 1 = 2

1+2 = 3

2+3 = 5

8+5=13

Explanation

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

we highlight the missing letter with a red color 

Explanation

1 x  1 + 1 = 2

2 x 2 + 2 = 6

3 x 3 + 3 = 12 

4 x 4 + 4 = 20 

5 x 5 + 5 = 30 

6 x 6 + 6 = 42

Explanation

We know that in a dictionary, words are arranged in alphabetical order.

First, we will arrange the letters of the word MOTHER in alphabetical order

Thus, we get E, H, O, M, R, and T.

Now, we know that the words starting with E will appear first in the dictionary.

Let us fix letter E as the first letter of the word.

Explanation

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

ANPL 

BOOK 

the next alphabet of A is B, N is O,

the before alphabet of P is O, K is L

so 

GZOE 

HAND 

the next alphabet of G is H, Z is A

the before alphabet of N is O, D is E

Explanation

6,

6×6=36,

7,

7×7=49,

5, 

5 x 5 = 25

Explanation

 A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

7 + 2 -1 = H

9 - 1 = 8 

H is the 8th number in the alphabetical series

22 + 6 -5 = W

28 - 5 = 23

W is the 23rd number in the alphabetical series

11 + 6 -2 = ?

17 - 2 = 15 

 O is the 15th number in the alphabetical series

Explanation

So in this way the next number in the sequence, 0, 3, 8, 15, 24, 35

From the given series the logic is adding odd numbers in the series

0 + 3 = 3

3 + 5 = 8

8 + 7 = 15 

15 + 9 = 24

24 + 11 = 35

Explanation

19 9 29 8 39 7

solution

19 +10=29

 9 -1=8

29+ 10=39

 8-1=7
