Answer:
Step-by-step explanation:
First term = a =4
Common difference = d = 2nd term - first term
d = 8 - 4 = 4
Last term = l = 400
First we have to fin the number of terms 'n'
l = a + (n-1)d
4 + (n-1)*4 = 400
4 + 4n- 4 = 400
4n = 400 {Divide both sides by 4}
n = 400/4
n = 100
What I like to do with negative numbers is count back from the positive to the negative here I can make a number line! :) think of it this way 0 is the middle of your positive and negative numbers it’s where they are coming together!
-5 -4 -3 -2 -1 0 1 2 3 4 5
