<span>Cross multiply
26*5x = 849 * 57
130 x = 48393
x = 48393 / 130
x = 372.25</span>
1 is 52 2 is 30 3 is 30 4 is 62 5 is 118
8, 3, -2, -7
basically
you have to figure how to get from one term to the other. so in this case, to get from 8 to 3, you have to minus 5. and same again to get from 3 to -2, you again have to -5.
so the first past of the answer is -5n.
then after that, you have to figure out how to get from -5, to the first term of your sequence. so you have to add 13, in this case.
your answer would then be
<h2>
<em><u>
-5n + 13</u></em></h2>
