Select the option in which the numbers share the same relationship as that shared by the numbers in the given set.
(12, 18, 225)
Answer & explanation
Correct answer: option 2
(12, 18, 225)
The logic followed here is :
{(Ist term + IInd term )÷ 2}2
As
{ (12 + 18 ) ÷ 2}2
{ 30 ÷ 2 }2
(15)2 = 225
similarly in option 2
(25, 15, 400)
{ (25 + 15 ) ÷ 2}2
{ 40 ÷ 2 }2
(20)2 = 400
