Answer:
1. 5, 11, 18, 26, 35, 45
Step-by-step explanation:
5, 11, 18, 26,
The difference between 5 and 11 is 6.
The difference between 11 and 18 is 7.
The difference between 18 and 26 is 8.
As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.
26 + 9 = 35
And the next difference would be 9 + 1 = 10.
35 + 10 = 45
