What is the explicit formula for this sequence? -5,-3,-1,1,3

Answer:
B
Step-by-step explanation:
a1 = -5
a2 = -3
a3 = -1
and so on
So since we start with -5 it will be -5+ something.
each time you add 2, but since the first one doesnt add anything we want n-1 times 2 so that leaves us with -5+(n-1)2
