?_.​

Answer 1

Answer: 1.21

Step-by-step explanation:

As they are taking prime numbers only,

.11 x .11 = 1.21

Answer 2

The next number is "equal to 1.21".

Step-by-step explanation:

We have,

0.04, 0.09, 0.25,  0.49,  ?

To find, the next term =

Odd places,

$\sqrt{first place} \times 2+.1$$=\sqrt{third place}$

Even places,

$\sqrt{second place} \times 2+.1$$=\sqrt{fourth place}$

$\sqrt{0.25} =0.5=\sqrt{0.04} \times 2+0.1=0.4+0.1=0.5$

$\sqrt{0.49} =0.7=\sqrt{0.09} \times 2+0.1=0.6+0.1=0.7$

Similarly/

?=\sqrt{0.25} \times 2+0.1=1.0+0.1=1.1\times 1.1=1.21[/tex]

The next number = 1.21

Hence, the next number is "equal 1.21".
