Write down in figures, seventeen thousand and seventeen.

Hint: Write in numbers using ones, tens etc. concept.

Complete step-by-step answer:
Here from the written number we can assume that seventeen is the place which occupies ones and tens place therefore at ones place there is $7$ and at tens place there is $1$, thereafter we can see that there is no terms which speaks about hundredth place and as we know it cannot be empty so there will be $0$ at the hundredth place and from the given question we can see that there is seventeen at the thousand and ten thousand place, so we can say that there is $7$ at thousand place and $1$ at ten thousand place.
So the number in sequence will be $17017$
Seventeen thousand and seventeen $ = 17,017$

Note: Whenever you are asked to write the written number in english in figures you have to write it in numbers as done above. Be attentive while writing, since sometimes we write different numbers when we are not attentive.
