Concept:The pattern is that the second number is obtained by multiplying the first number by 2 and then subtracting 4.Explanation:First, verify the pattern with the given pairs.For 705 : 1406 →
705
1406
(Num1)
(Num2)
(705×2)−4=1410−4=1406For 582 : 1160 →
582
1160
(Num1)
(Num2)
(582×2)−4=1164−4=1160Thus, the rule is confirmed: (First number × 2) − 4 = Second number.Now, apply this rule to find the missing number for ? : 230.Let the missing number be x.We have: (x×2)−4=230Add 4 to both sides: x×2=234Divide by 2: x=117Therefore, the missing number is 117.Answer:Option 1: 117
