Here is your answer -

1113213211

Explanation:

This is a look and say puzzle. next number we can find by just looking previous number. Two parts are there in each next number -

• 1 - only one time repetitions of 1 , so next = 11.
• 11 - two times repetition of 1, so next = 21.
• 21 - one time repetition of 2 and one time repetition of 1, so next =1211.
• 1211 - one time repetition of 1, one time repetition of 2 and two times repetition of 1, so next =111221.
• 111221 - three times repetition of 1, two times repetition of 2 and one time repetition of 1, so next =312211.
• 312211 - one time repetition of 3, one time repetition of 1, two times repetition of 2 and two times repetition of 1 so next =13112221.

Now for next term -

• 13112221 - one time repetition of 1, one time repetition of 3, two times repetition of 1, three times repetition of 2 and one time repetition of 1 so next = 1113213211.
