The following sequence is an arithmetic sequence. [-9, -2, 5, 12,...]
egoroff_w [7]

Answer: The common difference is 7, and the next two terms are 19 and 26.

Step-by-step explanation:

Between -9 and -2 there is +7, same with between -2 and 5, as well as 5 and 12. Adding 7 to 12 again gets 19, and adding 7 to 19 gets 26 as well for the next two terms.

The sum of two numbers is 3.1. Twice the large number is 7 more than 3 times the smaller number. What are the numbers?
Degger [83]

Let the two numbers be x and y where x is greater than y.

So;

x + y = 3.1 ... (i)

2x - 3y = 7 ... (ii)

This forms a set of simultaneous equations (i) and (ii)

Solving the simultaneous equations by elimination;

We multiply (i) by 2 and (ii)  by 1 to get:

2x + 2y = 6.2 ... (i)

2x - 3y = 7 ... (ii)

Subtracting (i) - (ii) we get;

5y = -0.8

y = -0.8/5 = -0.16

x = 3.1 - -0.16 = 3.26

The numbers are 3.26 and -0.16.
