Subsequent 6477

We will put 900 bags in 9 rows so that there are five fewer in each subsequent one. How much is in the first place?

Correct answer:

a1 =  120

Step-by-step explanation:

a1+\ldotsa9=900 s9=900 d=5 n=9  a9=a1+8d s9 =(a1+a9)/2 9 s9 =(a1+a1+8d)/2 9 a1=(s9 2/98 d)/2=(900 2/98 (5))/2=120 a2=a1+d=120+(5)=115 a3=a2+d=115+(5)=110
