Expert Answer:
let the first term and common diff of the A.P.be a and d resply.
Acc to formula for the sum of n terms we get,
(11/2)[2a+10d]=429
and
(23/2)[2a+22d]=1863
so we get, the equations are
11a+55d=429
and
23a+243d=1863
solve these to find the values of a and d.
from that you can get the terms of the A.P.
