Answer:
its 40
Step-by-step explanation:
The number added to the first term to get the next term is 0.
The number added to 2nd term to get the next term is 2.
And so on...
This pattern creates a sequence of:
0,2,4,6,8,?
which has a common difference of 2.
The next number in this sequence is 10, so we add 10 to 30 from the original sequence to get the next term.
30 + 10 = 40.
