Answer: 26
Step-by-step explanation:
to solve this series, we should find a pattern first.
if we look at the differences of each number, we can see that
4-1=3
8-4=4
13-8=5
19-13=6
to find the next number in the series, it would be 7 more than 19, since are counting upwards from 3.
Answer: 26
1 to 4 is 3
4 to 8 is 4
8 to 13 is 5
13 to 19 is 6
the next number should be 26
