Which of the following numbers will replace the question mark (?) in the given series?
2,14,70,210,?

Correct option is D

​The sequence given is: 2,14,70,210,?

We need to identify the logic connecting the numbers and find the next term.

Step 2: Analyze the relationships between consecutive terms

Relationship between $2$ and $14$:

Here, the second number is obtained by multiplying the first number by $7$.

Relationship between $14$ and $70$:

Here, the third number is obtained by multiplying the second number by $5$.

Relationship between $70$ and $210$:

Here, the fourth number is obtained by multiplying the third number by $3$.

Step 3: Identify the pattern

The multipliers between consecutive terms are:

The pattern shows that the multipliers are decreasing by $2$ each time:

Step 4: Apply the pattern to find the next term

To find the next term in the sequence, multiply $210$ by the next multiplier, $1$:

Final Answer:

The number that replaces the question mark is:D. 210

Thus, the complete sequence is:
