Find the next term in the sequence

6, 8, 11,15,20

Answer: 26

Step-by-step explanation: Each number adds + 1 as it goes to the next number. 6 to 8 shows a 2 increase. Then the next number gains a + 1 increase. So 8 to 11 is 3, then another + 1 increase. So 11 to 15

Another + 1. 15 to 20 (5 increase). and lastly a 6 increase, 20 to 26
