a,b,c,d,e,f are the five real number in A.P and a is 4 times of c and sum of all is 3
calculate value of e?
option are
9,-9,-3,-4
plz solve this q

• If the 3rd number is 2 then 1st one wil be 4*2=8. then the diference between 1st nd 3rd is 6. As it is in A.P. Common dfrnce can b 3. In that order the numbers will be 8 5 2 -1 -4 -7. The sum of all numbers is 3. So the 5th number is -4.

• Ans is -4
  Sol:a-2d,a-d,a,a+d,a+2d,a+3d are the 6 terms in ap
  Given sum of the six terms is 3
  I.e; 6a+3d=3 ----- eq1
  And 1st term is 4 times the 3rd term so
  a-2d=3a------- eq2
  Solving 1 and 2 you get a and d values
