For the series 16, 24, 36, 54,... find S7.

diamong [38]

24 - 16 = 8
36 - 24 = 12
54 - 36 = 18

So, obviously, this isn't an arithmetic sequence.

24/16 = 3/2
36/24 = 3/2
54/36 = 3/2

Aha! This is a geometric sequence.

Now, let's find the 7th term in this sequence!

$a_n = a_1 \cdot r^{n-1}$

We're trying to solve for a_7.
We know that a_1 is 16
We know that n = 7
We know that r = 3/2 or 1.5

Plug it in!

$a_n = a_1 \cdot r^{n-1}\\\\a_7 =16 \cdot 1.5^{7-1}\\\\a_7 = 16 \cdot 1.5^6\\\\a_7 = 16 \cdot 11.390625\\\\\boxed{\bf{ a_7 = 182.25}}$

The seventh term is 182.25

Is this table proportional or non proportional , How do you know?

Vlad [161]

Ez
This is non-proportional
There are 3 ways to figure out if a table is proportional or not
The one i used in which if u make fractions like 2/24. They should be equal to another fraction taken from your table
2/24 simplified is 1/12 while 8/36 is 2/9.
So

NON-PROPOTIONAL

Plz I need help with number 3 !!!

vovikov84 [41]

Well the ratio would be 8:24, or in reduced form, 1:3. you would solve it by taking sale of strawberry yogurt for the first half of the ratio, and then adding up all of the values to get the total.
