Please answer this three question.

Answer 1

9) Missing number (?) = 3.4

10) Missing number (?) = 84

Step-by-step explanation:

9) The given sequence are:

2.2, 6.1, 3.1, 5.2, 4.0, 4.3, 4.9, ?

To find, the value of missing number (?) =

The pattern follow:

The sum of pair of numbers = 8.3

2.2 + 6.1 = 8.3

3.1 + 5.2 = 8.3

4.0 + 4.3 = 8.3

Similarly,

4.9 + ? = 8.3

⇒ ? = 8.3 - 4.9 = 3.4

∴ Missing number (?) = 3.4

10) The patter follow:

First column = 3x + 1 and second column = 2x + 4

First column,

7 × 3 + 1 = 21 + 1 = 22, 22 × 3 + 1 = 66 + 1= 67, 67 × 3 + 1 = 201 + 1 = 202,

202 × 3 + 1 = 606 + 1 = 607

Second column,

7 × 2 + 4 = 14 + 4 = 18, 18 × 2 + 4 = 36 + 4 = 40

? = 40 × 2 + 4 = 80 + 4 = 84

84 × 2 + 4 = 168 + 4 = 172

∴ Missing number (?) = 84
