How to find nth term of a sequence in math?

worty [1.4K]

Salutations!

To find the nth term, you will be needing a formula.

$a +(n-1) *d$

a stands for the first term (first number in the sequence)

d stands for the difference between two terms. (always remember to subtract from the 2nd term to the 1st term)

and the n is what we are going to find

so in your sequence: 5, 10, 15, 20

5 is a (as it is the first term)

d would be 5 ( 10 -5 =5)

$a+(n-1)*d$

$5+ (n-1) *5$

$5+5n-5$

$5n+0$

your nth term is $5n+0$

Hope this helps!

Have a great day!

Oksana wrote the equation below on the whiteboard.

Kaylis [27]

Answer:

b = 7

Step-by-step explanation:

6 b + 6 = 48

Subtract 6 from each side

6b+6-6 = 48 -6

6b = 42

Divide each side by 6

6b/6 = 42/6

b = 7

What are the solutions of 3t + 2 < 7 or -4t + 5 < 1? Graph the solutions and put each solution in interval notation.

Ghella [55]

Answer:

$\displaystyle (-∞, 2\frac{1}{3}) ∪ (1, ∞) \\ \\ 2\frac{1}{3} > t \:OR\: 1 < t$

Step-by-step explanation:

3t + 2 < 7 OR −4t + 5 < 1

- 2 - 2 - 5 - 5

___________________

$\displaystyle \frac{3t}{3} < \frac{7}{3} \:OR\: \frac{-4t}{-4} < \frac{-4}{-4} \\ \\ t < 2\frac{1}{3} \:OR\: t >1$

**Whenever you divide\multiply by a negative integer, you reverse the inequality symbol given to you initially.

As you can see in the above graph, the graph is connected ALTOGETHER. Be aware that this will not ALWAYS be the case because a majourity of these graphs are seperated, pointing in OPPOSITE directions.
