Practice problem
What is the recursive formula of the sequence 123456,12345.6,1234.56,123.456,12.3456…?123456, 12345.6, 1234.56, 123.456, 12.3456\dots?123456,12345.6,1234.56,123.456,12.3456…?
an=(0.1)an−1a_n = (0.1)a^{n-1}an=(0.1)an−1
an=0.1an−1a_n = 0.1a_{n-1}an=0.1an−1
an=123456⋅0.1n−1a_n = 123456\cdot0.1^{n-1}an=123456⋅0.1n−1
an=0.1n−1a_n = 0.1^{n-1}an=0.1n−1
Type a concept, like “slope” or “photosynthesis”.
