An = a1 + (n − 1)d<br> Find the 31st term of the sequence -22, -19, -16, -13,...

JulsSmile [24]

Answer:

68.

Step-by-step explanation:

The common difference d = -19 - (-22) = 3

So the 31st term =

a31 = -22 + (31-1)3

= -22 + 90

= 90 - 22

= 68.

write a conjecture as to the number of sides as compared to the number of triangles formed when drawing diagonals from one verte

zmey [24]

Answer:The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previous term is even, the next term is one half the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.

Step-by-step explanation :an opinion or conclusion formed on the basis of incomplete information.

Which equation justifies why seven to the one third power equals the cube root of seven?

Rudiy27

The equation that justifies why seven to the one third power equals the cube root of seven is seven to the one third power all raised to the third power equals seven to the one third times three power equals seven

<h3>How to solve an equation?</h3>

using indices law,

$\sqrt[n]{x} = x^{1 / n}$

Therefore, let's justify

$7^{1/3} = \sqrt[3]{7}$

Hence, the justification is as follows;

$(7^{1 /3}) ^{3} =(7^{1/3})^{3} = 7$

Therefore, the justification of is that seven to the one third power all raised to the third power equals seven to the one third times three power equals seven
