For which of the following inequalities is x≥4 a solution.<br> x+3≥1<br> 3x≥1<br> x-3≥1
pychu [463]

Answer:

x - 3 ≥ 1

Step-by-step explanation:

Solving each of the inequalities

x + 3 ≥ 1 ( subtract 3 from both sides )

x ≥ - 2

3x ≥ 1 ( divide each inequality by 3 )

x ≥ \frac{1}{3}

x - 3 ≥ 1 ( add 3 to both sides )

x ≥ 4 ← required solution

Write down the nth term of the sequence 5, 8, 13, 20, 29
amid [387]
Hello! To find any number in the arithmetic sequence we can use a formula!

It is given by  a_n =a_1+(n-1)d


The geometric sequence formula goes by S_n =  \frac{a_1(1-r^n)}{1-r}

So for this we notice that there's a start of 5 and is being added 3 to get 8.

and then each time it is added by 2 more to get the next time

5
5+ 3 = 8
8 + 5 = 13
13 + 7 = 20
20 + 9 = 29
29 + 11 = 41
41 + 13 = 54
54 + 15 = 69 
69 + 17 = 83

Your formula is a_n = (n-1)^2 + 4&#10;&#10;
Where n starts at 2 not 1
