If the nth term of a number sequence is 2n + n, find the first 3 terms and
the 10th term.

1st 3

2nd 6

3rd 9

10th 22

Step-by-step explanation:

1st 2(1) +1 = 3

2nd 2(2) + 2 =6

3rd 2(3) + 3 = 9

10th. 2(10) + 10 = 22

I think this is how you solve it

i dont know sorry

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
