Classify the following sequence as arithmetic, geometric, neither or both: 2, 6, 18, ...

yan [13]

Answer:

Geometric

Step-by-step explanation:

Does multiplying the same number with each term give the next term?

If so, then it is Geometric Sequence.

Does adding the same number with each term give the next term?

If so, then it is Arithmetic Sequence.

We see that multiplying by 3 gives us each successive term. 2 times 3 is 6 and 6 times 3 is 18. So it is geometric sequence.

It is NOT arithmetic sequence since we add 4 to 2 to get next number 6, but we have 12 to get next number, which is 18. So not an arithmetic sequence.

Answer is "Geometric"

Please Help Me On These Questions!!!!!! I need Help!!!!!

1. This is one confusing question... But here is what I did
x = 2y + 1
y = $3y^{2}$ + 2x

So plug in Y to solve for X
x = 2 ( $3y^{2}$ + 2x) + 1
x = $-2y^{2}$ - $\frac{1}{3}$
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...

5. You have to find the multiples of 60 so...

1 60
2 30
3 20
4 15

where,

x and y are exchanged by coordinates given in qn

1,64a-8b+c=0

2,4a-2b+c=0

or c=2b-4a

60a-6b=0

140% of what number is 39? Provide an exact fraction answer.

Norma-Jean [14]

Answer:

27.86 or 27 wholes 6/7

Step-by-step explanation:

Let the number be x

140% of x = 39

140x/100 = 39

140x = 3900

x= 3900/140

x = 27 wholes 6/7 or 27.86
