Answer:

The nth term of sequence is 3n^{2}+7

Step-by-step explanation:

We need to find out the general recurrence relation of sequence:

10, 19, 34, 55

if we see pattern of sequence that every square of each number 'n' is multiple of 3 and addition of 7

check this pattern by 3n^{2}+7

For n=1

3n^{2}+7

3(1)^{2}+7

3+7

10

For n=2

3n^{2}+7

3(2)^{2}+7

3\times 4+7

12+7

19

For n=3

3n^{2}+7

3(3)^{2}+7

3\times 9+7

27+7

34

And so on..

Therefore, the nth term of sequence is 3n^{2}+7

Please help with the question attached. I really need help! Thanks!
horsena [70]

To solve this question you would first multiply all the dimensions of the pillar together. That would be:

2.5 x 2.5 x 12 = 75 square feet

Then you take the weight of the pillar and divide it by the amount of square feet:

12,000 / 75 = 160 pounds per square foot.

Oliver picks a 4-digit even number that is greater than 3000.
Irina18 [472]

Answer:

Hello,

why not 700 ?

Step-by-step explanation:

n=\overline{abcd}\\a\in \{3,4,5,6,7,8,9\}: 7\ possibilities\\b\in\{4,8\} :2\ possibilities\ :0 \ in\ USA\  is\ not\ a\ multiple\ of\ 4\\c \in\{0,1,2,3,4,5,6,7,8,9}: 10\ possibilities\\d \in \{0,2,4,6,8\}:5\ possibilities\\

7*2*10*5=700

Impossible to reach 3000 since 2nd digit is 4 or 8.
