Answer:

-46

Explanation:

(hello, I just answered your previous question--some stuff will sound similar because we are applying the same concept :) )

We know that the nth term of the sequence is 18 - 8n

the "nth" term of a sequence means that you can plug in the term place to get the term value (ex. if the nth term is n + 2, we can plug any term in {let's say, the eighth term, 8 + 2 = 10 ; to get our term's value} )

18 - 8n is sequence

18 - 8(8) is 8th term

18 - 64 is 8th term

-46 is the 8th term

hope this helps!! :)
