What is the next number in sequence 7, 2, 0, 7, 8, 4, 3,?

To solve for the next number, we need to assign a variable for the unknown number and let that be equal to X.

Then we have the solution below:

7+2+0+7=16

2+0+7+8=17 where 17=16+1

0+7+8+4=19 where 19=17+2

7+8+4+3=22 where 22=19+3

8+4+3+x=26 where 26=22+4

Therefore, the value of x is 11.
