Question

Margot and Francois were doing their algebra homework when Margot's dog, Pepe, bit off a piece of the paper they were working on. All they had left was a part of the sequence: 6, 12, ... and the fact that 1536 was another term of the sequence. Assuming the sequence is arithmetic, what term number is 1536 ?

Answer 1

Second Part

Assuming the sequence is geometric, what term number is 1536 ?

Answer 2

arithmetic ... the difference is 6

(1536 - 12) / 6 = ?

12 is the 2nd term ... 1536 is the (?+2) term


geometric ... the ratio is 2

12 * 2^? = 1536

1536 is the (? + 2) term
