common difference = A2A1 = A3A2 = 11

A3A2 = 11 2n  (n1) =11 can you find 'n' from here ??

A2  A1 = 11 (n  1)  (n 5) = 11 1 + 5 = 11 no. 4 does not equal 11.

ok...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'.

common diff. always remains constant/same!

Yep, common difference of 4 works here.

Note 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.

WHAT IF THE COMMON DIFFERENCE IS 9??

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