Endospores are hardy, defensive structures that enable some bacteria to survive harmful environmental conditions, such as starvation, high temperatures, desiccation (drying out), chemical disinfectants and extremes in pH.
Recursive formula is a formula that is used to determine the next term of a sequence using one or more of the preceding terms.
Recall that an explicit formula for a pattern is a formula that gives the n th term in the pattern in terms of n. An explicit formula for the pattern in this example is f(n)=2 n !1. Exercises: Use functional notation to write a recursive formula for each of the following patterns. 1.
