Answer:
See below ~
Step-by-step explanation:
The pattern that can be seen here is that each consecutive term increases 1 more than the value the previous term was increased by.
As we can see here :
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
Let the unknown term be aₙ the term that precedes it be aₙ₋₁, and the common difference of the previous term dₙ₋₁. Then the rule here would be :
aₙ = aₙ₋₁ + (dₙ₋₁ + 1)
