Write an explicit formula for the arithmetic sequence whose common difference is -18
drek231 [11]

Let the first term be a(0).  Then the formula for a(n) is a(0)-18(n-1).

Check:  What's the first term?  Let n = 1:  a(1) = a(0)-18(1-1) = a(0) (correct)

What's the second term?    Let -n =2:  a(2) = a(0)-18(2-1) = a(0) - 18

and so on.

Como resolver y=1-2.5
oksian1 [2.3K]

I don't really speak Spanish but I'll guess that says

 How do I solve  y = 1 - 2.5

Unless I'm missing something, there's not even any algebra here.  

The way we subtract a bigger number from a smaller number is first we subtract the smaller number from the bigger number the regular way, then we prepend a minus sign.


y = 1 - 2.5 = -(2.5 - 1) = -1.5
