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
1/8 .All you have to do is divide 1/4 by two and you get 1/8. If you want a decimal it would be 0.125
