Missing Number in Number Series
Given number series is 2, 30, 320, 3230, ____.
We have to find the missing number from the given options.
Solution:
Let's observe the number series carefully:
- The first number is 2.
- The second number is obtained by multiplying the first number by 15 and then adding 0. That is, 2 × 15 + 0 = 30.
- The third number is obtained by multiplying the second number by 10 and then adding 20. That is, 30 × 10 + 20 = 320.
- The fourth number is obtained by multiplying the third number by 10 and then adding 300. That is, 320 × 10 + 300 = 3230.
Therefore, we can conclude that each subsequent number in the series is obtained by multiplying the previous number by 10 and then adding a certain constant to it.
Let's find out the constant:
- The constant between the first and second numbers is 0.
- The constant between the second and third numbers is 20.
- The constant between the third and fourth numbers is 300.
We can see that the constants are increasing by a factor of 10 each time. Therefore, the constant between the fourth and fifth numbers should be 4000 (i.e., 3000 × 10 + 400).
Hence, the missing number in the series is 32300.
Therefore, option (c) is the correct answer.
Note: None of the given options match with the missing number in the series, so the correct answer is (d) none.
