Best ResponseYou've already chosen the best response.3A3A2 = 11 2n  (n1) =11 can you find 'n' from here ??

Best ResponseYou've already chosen the best response.0A2  A1 = 11 (n  1)  (n 5) = 11 1 + 5 = 11 no. 4 does not equal 11.

Best ResponseYou've already chosen the best response.3ok...i guess, 11 as common difference(d) should naot have been given. in that case d = A2  A1 = 4 then A3A2 = 4 and find 'n'.

Best ResponseYou've already chosen the best response.0Note that we can't guarantee these are the correct answers, since... the question claims the difference is 11. Either that's wrong, or you didn't write out the question correctly.

Best ResponseYou've already chosen the best response.0WHAT IF THE COMMON DIFFERENCE IS 9??

Best ResponseYou've already chosen the best response.3from d = A2  A1 the common diff. must be 4 cannot be anything else.
