Practice problem
Find the recursive formula for 0.3,0.03,0.003,0.0003,⋯0.3,0.03,0.003,0.0003, \cdots0.3,0.03,0.003,0.0003,⋯
an=0.3an−1a_n = 0.3a_{n-1}an=0.3an−1
an=0.1an−1a_n = 0.1a_{n-1}an=0.1an−1
an=0.3n−1a_n = 0.3^{n-1}an=0.3n−1
an=0.1n−1a_n = 0.1^{n-1}an=0.1n−1
Type a concept, like “slope” or “photosynthesis”.
