Answer:
Depends on what sequence it is. For geometric it's 7/5 and for arithmetic - 2
Step-by-step explanation:
For n = 3:
a, = 1*2*3 - 1 = 5
For n = 4:
a, = 8 - 1 = 7
These are the terms for n = 3 and n = 4 but the thing is, this could be both geometric sequence and arithmetic sequence, since you didn't specify, here are the possible answers:
For geometric sequence, the rate of change is equal to An / An-1 therefore:
r = 7 /5
For arithmetic sequence, it's equal to A2 - A1 = 7 - 5 = 2
