b(n) = b(n − 1)• (-3)
What is the 4th term in the sequence?

  405

Step-by-step explanation:

The first term is 15 and each successive term is 3 times the last. So, the next three terms are ...

  15·3 = 45

  45·3 = 135

  135·3 = 405

The fourth term of the sequence is 405.

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
