Question
The number belongs in the blank is?
18, 24, ___,36, 42
- 28
- 31
- 30
- 35
Hint:
Check the difference between the numbers.
The correct answer is: 30
18, 24, ___,36, 42
The difference between each number is 6.
The rule for this sequence is to add 6 each time.
The missing number in the sequence: 24 + 6 = 30.
The given sequence: 18, 24, ___,36, 42
18, 24, ___,36, 42
The difference between 18 and 24 is 6. (24-18=6)
Similarly, the difference between 42 and 36 is 6. (42-36=6)
Therefore, the difference between the blank and 24 will also be 6. (__-24=6)
Only option (b) satisfies this.The correct option is (b) 30.
