Answer:
aₙ = 30 - 5n
Step-by-step explanation:
25,20,15,10, ...
<u>We see from the given series that it is AP with:</u>
- First term = 25
- Common difference = -5 and it is decreasing series
<u>Then formula is:</u>
- aₙ= a₁ + (n-1)d
- aₙ= 25 + (n-1)(-5)
- aₙ= 25 - 5n + 5
- aₙ = 30 - 5n
Not sure does anyone know what -26 - (-9 4/5) is I need help!!!!
You multiply the area of the triangle by 2
