Please help me with this :( :(
Use the equation to solve the problem.​

Suppose the first five terms of a sequence are 4, 5, 9, 27, 123. how could the next term in the sequence be generated?

Given the function f(x) = 3x + 1, evaluate f(a + 1). a. 3a + 1 b. a + 2 c. 3a + 4

Which equation represents the partial sum of the geometric series?
