Answer 1

Given:

9 8 15

6 4 2

6 10 x

To find:

x=?

Solution:

9 8 15

6 4 2

6 10 x

Formula:

$\bold{(\ first \ element - \ last \ element ) \times 2= \ mid \ term}$

Solve the value (9, 6, and 6):

$\to (9-6)\times2=3\times2=6$

Solve the value (8, 4, and 12):

$\to (8-10)\times2=-2\times2=-4$

Solve the value (15, 2, and x):

$\to (15-x)\times 2=2\\\to (15-x)=\frac{2}{2}\\\to (15-x)=1\\\to 15-1=x\\\to x=14$

In this question choices were incorrect. so, the final answer is "14".

Answer 2

Answer:

25

Step-by-step explanation:

(9-6)=03

0+3=3

3×2=6

(10-8)=02

0+2=2

2×2=4

(25-10)=10

1+0=1

1×2=2
