Arithmetric Sequence word problem. Thanks

Click For Summary
SUMMARY

The discussion focuses on solving a word problem involving the distribution of 100 loaves of bread among 5 people in an arithmetic sequence. The first two individuals together receive 1/7 of the total loaves allocated to the remaining three. The solution involves defining the quantities as a1, a1+d, a1+2d, a1+3d, and a1+4d, and establishing a system of linear equations to find the values of a1 and d. Participants are encouraged to derive the relationships between the quantities received by each group to formulate the necessary equations.

PREREQUISITES
  • Understanding of arithmetic sequences and their properties

Homework Statement



Ok here is the problem:

100 loaves of bread are to be distributed such that the quantities form an arithmetric sequence, among 5 people. The first 2 together receive 1/7 of the remaining 3, together. How much (loaves and fractions) does each receive?




Homework Equations





The Attempt at a Solution



So, I have this as the form:

a1, a1+d, a1+2d, a1+3d, a1+4d

Is that correct?

How do I get d?

Any help on solving this would be great. Thanks!

How much do the first two receive? How much do the remaining three receive? What is the relationship between these two quantities? This will give you one equation for a1 and d.

How much do all the people receive (in terms of a1 and d)? This will give you another equation.

Solve this linear system of two equations with two unknowns w.r.t. a1 and d.
