<em><u>See</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>image</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>solution</u></em>
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
