Answer:

The nth position in the sequence is the number in the nth term of the sequence.

Explanation:

Basically nth term is the expression itself. In mathematics nth term is expressed in the form of n which is actually the expression itself.

The nth term corresponds to the value of n. If n = 3 and the expression is 2n, then the nth term would be 6 (2x3). All expressions given in the question may have their own nth term based on the value of n. Let’s have a look at these examples:

When n = 5,

- 2n + 2 = 2(5) + 2 = 12

- 2n = 2(5) = 10

- 3n – 1 = 3(5) - 1 = 14

- 3n + 3 = 3(5) + 3 = 18

- 4n = 4(5) = 20

An athlete complains of weakness, rapid weight gain and muscle spasms. What may be the cause
hichkok12 [17]

The reason the athlete would have these complaints would be due to the fact that they are loaded on carbs.

<h3>What is carb loading?</h3>

This is used to refer to the fact that the athlete is taking too much of meals that are made up of carbohydrates.

Carbohydrates are heavy foods. They may cause the person to gain weight in a rapid way and also lead to weakness.

Excessively having carbs in your diets may also bring about other types of health issues such as:

  • A great increase in your blood sugar level.
  • It call lead to fat because your body would save the excess glucose as fat.
  • This may be one of the causes of diabetes in a person if they fail to take care of the fact that they are controlling carbs in a way that is unhealthy.
  • It could cause sluggishness.
  • For other people it may result in the outbreak of acne on their faces.

Jack invested $500 in the shares of a company x and $750
-BARSIC- [3]

Assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3

First step is to calculate x return on investment

x return on investment = $600 - $500

x return on investment= $100

Second step is to calculate y return on investment

y return on investment= $900 - $750

y return on investment= $150

Now let determine the ratio of return on investment from company x to that from company y

Using this formula

Ratio of return on investment=x return on investment/y return on investment

Let plug in the formula

Ratio of return on investment=100/150

Ratio of return on investment=2/3

Ratio of return on investment=2:3

Inconclusion assuming he sold all the shares of both companies for $600 and $900 respectively. what the ratio of return on investment from company x to that from company y will be is : 2:3
