The second question is number 3 for the polygon translation.
Question 3 is 2 units right and four units down.
Sorry I don’t know the answer hope you find one bye halleluja
Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.
Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9
ratio is not constant, so no.
The answer is (c) neither geometric nor arithmetic
A^2 - b^2 = (a+b)(a-b)
answer :
t^2 - 1
n^2 - 225
