Answer:
option 1!
Step-by-step explanation:
it started at 15 and ended at 23. also when u look at the sequence, 19 is in the middle. which shows in the graph that 19 is matching the line. but u might be confused since option 2 also has 19 matching the line... but look carefully. the square started at 17, but the sequence does not have 17 in it.
i hope this helped :D
