10	12	14
10	12	14
14	16	?
11	13	?

• A. 14,18
• B. 22, 20
• C. 18, 15
• D. 45639

Answer 1

The Correct Option is C

To solve the problem of identifying the missing numbers in the given table, let's examine the pattern followed by the numbers. We notice several rows of numbers in a 3xN arrangement: 

9	11	13
13	15	17
10	12	14
10	12	14
14	16	?
11	13	?

Let's analyze the sequence:

1. The first row shows the consistent increment pattern from 9 to 11, then 11 to 13. The increment value is 2.
2. The same pattern follows for the second row: 13 to 15, then 15 to 17.
3. The same increment pattern repeats for the third and fourth rows, i.e., 10 to 12, then 12 to 14.
4. This pattern of increment continues for the fifth row from 14 to 16.

Now, apply the same logic to find the last number in the fifth row.

1. Keep adding 2 to 16 to get 18, therefore 14, 16, becomes 18.

Now check the pattern for the sixth row:

1. This row starts with the number series from the first column of the previous row with an increment of 3 from 11 to 13, which would then go to the missing number.

So, in this row:

1. We have 11, 13; hence, following the pattern of increasing by 2 (from 11 to 13), the number next would be 15.

Therefore, the missing numbers are 18 in the fifth row and 15 in the sixth row. This corresponds to the option 18, 15.
