Answer 2

Answer:

Step-by-step explanation:

sum of three bags =93

sum of n bags = 341

so s3= n/2 (2a+(n-1)d)

93= 3/2 (2a+(n-1)d)

93/3 = 1/2 (2a+(n-1)d = 1/2 (2a+(3-1)d

31 =1/2 ×2 (a + d)

31 = a+d

similarly

341×2 = n (2a + dn - d)

682= n (2(31-d) + dn -d

682 = n ( 62 - 3d + dn)

682 = 62n -3dn + dn^2

then solve by splitting middle term method
