Question

Observe the pattern of the given series and fill in the blanks:

$9,109,209,\_,\_,\_$

Answer 1

The given pattern is $9,109,209,\_,\_,\_$

It can be observed that from the given pattern that the difference between two consecutive number $=\left(109-9\right)=\left(209-109\right)=100$

The next term in the series can be obtained by adding $100$ to the immediate previous term.

Therefore, next three terms are:

$$\begin{gathered} 209+100=309 \\ 309+100=409 \\ 409+100=509 \end{gathered}$$

Hence, the next three terms in the given pattern is $309,409,509$.
