Question:- in a flower bed there are 23 rose plants in the first row 21 in the Secend,19 in the thrid and so on there are 5 rose plants in the last row how many roseare there in the flower bed???

Answer:- Here a=23 ; d= -2 and an=5

an = a + (n-1)d

-->5 = 23 + (n-1)-2

-->5 = 23 +2 -2n

-->5 = 25 -2n

--> -2n = -20

-->n=10
