Question

State whether the following sequence is arithmetic, geometric, or neither.
10, 10.25, 10.50625, 10.76890625, .... (Points : 1)
arithmetic sequence
geometric sequence
neither

Answer 1

1. check if 10.25-10 = 10.50625 - 10.25 , if true then AS
2. check if 10.25/10 = 10.50625/10.25 , if true then GS

if both are false, then "neither"
if one is true, verify with the other given value.

Answer 2

Arithmetic sequence
