For all even numbers n, h(n) is defined to be the sum of the even numbers between 4 and n, inclusive. What is the value of h(12)/h(10) ?
Choose the correct choice from the following options
A) 1.8 B) 3 C) 6 D) 1.5 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(12) = [(4+12)/2]*5 = 40   h(10) (4+12)/2 *5=

<output>40</output>
40   h(10)= (4+10)/2]*4 = 28   h(12)/h(10) (4+10)/2 *4=

<output>28</output>
28   h(12)/h(10)= (40) / (28) ~ 1.5   Answer : 1.5
