From this sequence we can see that it is betting larger by 5 every single time.
So we can infer that the n = 5.
But we also have to add a number after that because right now the sequence would be 5,10,15,20. We need to find out how we get to 2 from 5n.*
*2 is the first number in the sequence
And to get 2 from 5 you simply subtract the number 5 by 3. So you end up with 5n - 3
Now that you have the nth term just substitute the term you want to find out so in this instance it is 40. 40 * 5 = 200 and then you take away 3 so It the answer must be 197. Hope this helps

How do i solve 3x-5y=9;x=-1,0,1
REY [17]
For x = -1, 3(-1) - 5y = 9 => -3 - 5y = 9 => 5y = -3 - 9 = -12 => y = -12/5 = -2.4
for x = 0, 3(0) - 5y = 9 => -5y = 9 => y = 9/-5 = -1.8
for x = 1, 3(1) - 5y = 9 => 3 - 5y = 9 => 5y = 3 - 9 = -6 => y = -6/5 = -1.2
