Question

2, 5, 11, 23, ____, ______, _______, _______, ________. Conjecture:​

Answer 1

2, 5, 11, 23, 47, 95, 191, 383, 767.

Explanation:

This sequence is 2, 5, 11, 23, 47, 95, 191, 383, 767 because as you may notice, 2+ 3 =5, double the 3 to get 6. 5+ 6 =11, double the 6 to get 11 + 12 =23, etc.

Double the factor and add it to the previous term to get your next term and so forth.
