Drpends upon the value of x

Step-by-step explanation:

When we add odd numbers we get either odd or even numbers

Like, 1+3=4

But, 1+3+5=9

Answer 2

Step-by-step explanation:

The number of digits added collectively is always equal to the square root of the total number.

• Sum of first odd number = 1.

The square root of 1, √1 = 1, so, only one digit was added.

•Sum of consecutive two odd numbers = 1 + 3 = 4.

The square root of 4, √4 = 2, so, two digits were added.

•Sum of first three consecutive odd numbers = 1 + 3 + 5 = 9.

The square root of 9, √9 = 3, so, three digits were added.

•Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16.

The square root of 16, √16 = 4, so, four digits were added.
