Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is the following:

In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:

The sum of the first n terms of an arithmetic sequence is given by:

In this question:

We want the sum of the first 37 terms, so we have to find 




Then

The sum of the first 37 terms of the arithmetic sequence is 2997.
Answer:
(6,4)
Step-by-step explanation:
y = x-2
y =4
Set the two equations equal
x-2 =4
Add 2 to each side
x-2+2 = 4+2
x =6
Now we need to find y
y =4
(6,4)
