Working backwards again:
3/2= 1.5
1.5 is the second term.
1.5/2= .75
.75 is the first term.
Answer:
( x - 3i ) ( x + 3i )
= x^2 + 3xi - 3xi - 9i^2
= x^2 - 9 (-1)
= x^2 + 9
(x^2 + 9 ) ( x + 5 )
Now the left hand side is equal to the right hand side.
Good luck!

Answer:
91
Step-by-step explanation:
When x goes from 1 to 2, y increases by 4 from -5 to -1
When x goes from 2 to 3, y increases by 5 from -1 to 3
We are adding 4 each step
The formula for an arithmetic sequence is
an = a1 + d(n-1)
where a1 is the first term a1 =-5
d is the common difference or what we add each time = 4
and n is the term number n=25
a25 = -5 + 4(25-1)
a25 = -5+4(24)
-5 +96
91
The 25th term is 91
