In a sequence of numbers, a4=3, a5=5, a6=7, a7=9, and a8=11. Which recursive rule can be used to find the nth term of the sequence, an?

a1=3; an=an−1+2
a1=−3; an=2an−1
a1=3; an=2an−1
a1=−3; an=an−1+2

a1=−3; an=an−1+2

Step-by-step explanation:

I just took the quiz and this was what was correct

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

why can't you?
