What Is the square root of 9

Genrish500 [490]

the square root of 9 would be 3. as 3 x 3 =9

the square root of any number is asking what number times itself will give you the given number you are trying to square root. for example, the square root of 36 would be 6, as 6 x 6 = 36. I hope this helped

Here are the first four terms of a quadratic sequence

mixer [17]

Answer:

2n² + n

Step-by-step explanation:

<u>Given sequence</u>:

3, 10, 21, 36, ...

Work out the first differences between terms:

$3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36$

As the <u>first differences</u> are <em>not </em>the same, work out the second differences.

$7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15$

As the second differences are the <u>same</u>, the sequence is quadratic and will contain an n² term.

The coefficient of n² is always <u>half of the second difference</u>. Therefore, as the second difference is 4, the coefficient of n² is 2.

To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:

$\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}$

Therefore, we need to add n to 2n² to match the sequence.

Therefore, the nth term of this sequence is 2n² + n.
