Sameer is collecting stamps. On the first day of the month, he is given 10 stamps. Each week after than he gets 15 more stamps. Which of the following equations defines how many stamps he has after the nth week? 5n + 5

10n + 5

15n - 5

5n + 15

15n-5 is your answer.

Step-by-step explanation:

1st week => 10 stamps

2nd week => 10 + 15 => 25 stamps

3rd week => 25 + 15 => 40 stamps

common difference = 15

Now,

an = a + (n - 1)d

or, nth week = 10 + (n - 1)15

nth week = 10 + 15n - 15

nth week = 15n - 5

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
