10 because 7 x 3 = 21 and 7 + 3 = 10 so your answer is 10

The only factors of 21 are: 1 and 21 or 3 and 7.

Since the two number mentioned are single digits, the numbers being used must be 3 and 7.

To get the sum, just add them together!
3 + 7 = 10

The answer to your problem is 10.

Hope this helps!!

13. For the arithmetic sequence: 6, 12, 18, 24,...
serg [7]

a_15 = 90

a_n = 6n

Step-by-step explanation:

Given sequence is:

6, 12, 18, 24,...

First of all we have to find the common difference. The common difference is the difference between consecutive terms of an arithmetic sequence.

Here,

d=a_2-a_1 = 12-6 = 6\\d=a_3-a_2= 18-12 = 6

The general form for arithmetic sequence is:

a_n=a_1+(n-1)d

Putting the values for a_1 and d

a_n=6+(n-1)(6)\\a_n=6+6n-6\\a_n=6n

<u>a) Find a15</u>

a_{15} = 6(15)\\=90

<u>b) Write an equation for the nth term.</u>

The equation is: a_n=6n
