Select the option that is related to the third number in the same way as the second number is related to the first number.
18 : 163 : : 24 : ?
Answer & explanation
Correct answer: option 2
18 : 163 : : 24 : ?
The logic followed here is :
Ist number × ( Ist number ÷ 2) + 1 = IInd number
As
18 × ( 18 ÷ 2) + 1
18 × 9 + 1
162 + 1 = 163
Similarly
24 × ( 24 ÷ 2) + 1
24 × 12 + 1
288 + 1 = 289
