This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.
X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
The answer is definatly C but if you know the answer why did you ask???
Anyway, hope this helps, and please mark brainliest!!!!!!!!!!!
25 is the number. Hope this helps.
