Which expression defines the arithmetic series 1 + 3 + 5 + . . for seven terms?

1+3+5+7+9+11+13+15+17+19 is the answer

Hope this helps!!! :3

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
