First number =(Secondnumber+1)4−14 Second number = 5 First number =(Secondnumber+1)4−14=(5+1)4−14=64−14=1296−14=1282 Similarly, Third number =(FourthNumber+1)4−14 Fourth number =6 Third number =(Fourthnumber+1)4−14=(6+1)4−14=74−14=2401−14=2387 So, 1282 : 5 :: 2387 : 6 Hence, the correct answer is "2387".
