30,____, 19, 13 1/2 whats the missing number?
scoray [572]
24.5 should be the missing number. 13.5 (13 1/2) + 5.5 is 19. 19 + 5.5 is *24.5*. 24.5 + 5.5 is 30. Basically, you go up by 5.5 every number.

The following is an arithmetic sequence that has 10 numbers LaTeX: 1,\ a_2, \ a_3, \ a_4, \ \cdots,\ a_{10}.1 , a 2 , a 3 , a 4
Naddika [18.5K]

Answer:

a_2=3

Step-by-step explanation:

The arithmetic sequence is given as: 1,\ a_2, \ a_3, \ a_4, \ \cdots,\ a_{10}

We are told that the 10 numbers add up to 100.

S_n=\frac{n}{2}(a_1+l)\\ $Where: \\n=number of terms\\l=last term\\a_1$=first term

S_{10}=100\\100=\dfrac{10}{2}(1+l)\\100=5(1+l)\\$Divide both sides by 5$\\20=1+l\\$Last term, $l=20-1=19

We know that the nth term of an arithmetic sequence

l=a_1+(n-1)d\\19=1+(10-1)d\\19=1+9d\\9d=19-1\\9d=18\\d=2

Therefore, the second number

a_2=a_1+2\\=1+2\\a_2=3

A parallelogram has a base of length x + 7 and a height of x + 2 and has an area of 50 square units. find the base and height of
diamong [38]
Substitute in what you already know into the formula, since the formula is (a=bh) you already know what A is so now you have 50=bh, now the length is x+7 , length is basically height , so h in the formula , so now you get 50=b(x+7) , now you need b luckily you already have b, so plug in 50=(x+2)(x+7) , you can guess and check or you can solve for x by double distributing
