Answer:
the answer is -10
Step-by-step explanation:
Its basically multiplication
4 = 7 - 3
1 = 4 - 3
-2 = 1 - 3
-5 = -2 - 3
=> An = A (n-1) - 3, where A1 = 7
The next term is A6 = A5 - 3 = - 5 - 3 = - 8
So the answer is the fourth option.
Mean-20.3+12.5+7.9+17.5+15.6+14.1= 87.6
87.6/6=20.1
Median- 7.6+17.5/2= 12.55
No. A squared plus b squared must equal c squared (Pythagorean theorem). 10 squared is 100, 12 squared is 144, they add up to 244 but 22 squared is 484…..much too large
