 The th element of the -nacci sequence is given by
where formula_67 denotes the nearest integer function and formula_75 is the formula_7-nacci constant, which is the root of formula_74 nearest to 2.A coin-tossing problem is related to the formula_7-nacci sequence.The probability that no formula_7 consecutive tails will occur in formula_58 tosses of an idealized coin is formula_100.
