For all even integers n, h(n) is defined to be the sum of the even integers between 6 and n, inclusive. What is the value of h(18)/h(10) ?
Choose the correct choice from the following answers:
A) 1.8  B) 4  C) 6  D) 18  E) 60
CONCEPT: When terms are in Arithmetic Progression (A.P.) i.e. terms are equally spaced then   Mean = Median =(First+Last)/2   and Sum = Mean*Number of terms   h(18) = [(6+18)/2]*7 = 84   h(10) (6+18)/2 *7=

<output>84</output>
84   h(10)= (6+10)/2]*3 = 24   h(18)/h(10) (6+10)/2 *3=

<output>24</output>
24   h(18)/h(10)= (84) / (24) ~ 4   Answer : 4
