What is the nth term of the following sequence……… 8, 3, -2, -7………..explain clearly aswell
Sphinxa [80]

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>
