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.
(The number you add or subtract.) 3. Create a recursive formula by stating the first term, and then stating the formula to be the precious term plus the common difference. a1 = first term; an = a n-1 + d. a 1 = the first term in the sequence an = the nth term in the sequence.
