Answer:
13
Step-by-step explanation:
a = 5
b = -8
5 - -8 = 13
38 is the answer because 25+13=38
Let's call the two numbers a and b. So we know that the difference of the two numbers is 36:
a - b = 36
And we know that their sum is 286:
a + b = 286
We can use either of these equations to solve for one of the variables in terms of the other variable. Let's use the first and solve for a:
a - b = 36
a = 36 + b
Now we plug this into the other equation and solve for b there:
(36 + b) + b = 286
36 + 2b = 286
2b = 250
b = 125
Answer:
arithmetic sequence
Step-by-step explanation:
There is a common difference between consecutive terms , that is
d = 7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3
This indicates the sequence is arithmetic with common difference d = 3
