Answer:
4.5
Step-by-step explanation:
original number subtracted by the original number divided by 10
The arithmetic sequences are 3rd one, and 5th one as they are increasing or decreasing by a constant rate of change
First term =a1=5
common difference=7.5-5=10-7.5=2.5
so an=a1+(n-1)d
so
an=5+(n-1)*2.5
an=5+2.5n-2.5
an=2.5+2.5n
