Question

Please help!
Find the first six terms of the sequence.

a1 = 6, an = 2 • an-1

Answer 1

6, 12, 14, 16, 18, 20

12, 24, 48, 96, 192, 384

0, 2, 12, 14, 16, 18

6, 12, 24, 48, 96, 192

Answer 2

@phi could you help with this one?

Answer 3

the rules are
\[ a_1= 6 \\a_n= 2 a_{n-1} \]
the little number in the bottom right is the number of the term. in other words
\(a_1\) means the first term in the sequence.

that should be a clue as to which of the 4 choices are wrong (because they do not start with 6)
