Answer: -19
Step-by-step explanation:
Seriously... anyway u already know 4 out of the 30 terms of the sequence. U just count back 26 more numbers. I’ll elaborate further 4 u. Keep in mind u already counted 10,9,8 and 7
6,5,4,3,2,1,0,-1,-2,-3,-4,-5,-6,-7,-8,-9,-10,-11,-12,-13,-14,-15,-16,-17,-18,-19
Since u already counted 10,9,8 and 7 you realize that the 30th number is -19.
No need to thank me. Anything 4 my friends ;)
