 -x + y = 4
<u>2x + y = 1</u>
    <u>-3x</u> = <u>3</u>
     -3    -3
       x = -1
   -x + y = 4
-(-1) + y = 4
     1 + y = 4
 <u> - 1         - 1</u>
           y = 3
(x, y) = (-1, 3)

Write an equation to find the nth term. Then find ₐ₂₄<br> 1, 3, 5, 7,.......
kirill115 [55]

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is 1 and d is the difference, which in this sequence the next term is found by adding 2 to the previous term, so d = 2 and n is the term you want to find.

The equation is:

an = 1 + (n-1)2

a24 = 1 + (24-1)2 = 1 + 23(2) = 1+46 = 47
