Answer:
-149
Step-by-step explanation:
=-11 + (n - 1)(-3)
by observation
when n = 0,
= 1st term
when n = 1,
= 2nd term
.....
when n = x,
= (x+1)th term
hence if we want to find the 48th term, n = 48 - 1 = 47
when n = 47,
= 48th term
= -11 + (47-1)(-3)
= -11 + 46(-3)
= - 11 - 138
= -149
X-5, y+9
because -5 then positive 5 up

Answer:423 208 8819
Step-by-step explanation:
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
