### Solution:

**#1 Question:**

1, 6, 15, ?, 45, 66, 91

The given sequence follows the patterns: +5, +9, + 13, +17, +21, +25, and so on…

So, the missing number is = 15 + 13 = 28

Hence, the answer is d) 28.

**#2 Question:**

2, 5, 9, 19, 37, ?

Clearly, we have the pattern:

2 x 2 + 1 = 5,

5 x 2 – 1 = 9,

9 x 2 + 1 = 19,

19 x 2 – 1 = 37, so on

Therefore; 37 x 2 + 1 = 75

Hence, the answer is b) 75

**#3 Question:**

6, 13, 25, 51, 101, ?

The pattern is;

x 2 + 1,

x 2 – 1,

x 2 + 1,

x 2 – 1,

x 2 + 1,

x 2 – 1, so on…

So, the missing term is; 101 x 2 + 1 = 203

Hence, the answer is c) 203

**#4 Question:**

2, 3, 8, 27, 112, ?

The pattern is:

x 1 + 1,

x 2 + 2,

x 3 + 3,

x 4 + 4, so on…

So, the missing number is; 112 x 5 + 5 = 565

Hence, the answer is d) 565

**#5 Question:**

1, 4, 10, 22, 46, ?

The pattern is; +3, +6, +12, +24, so on…

So, the missing term is = 46 + 48 = 94
