Step-by-step explanation:
a,Arithmetic sequence=12,23,34
Common difference= 1st term - 2nd term
= 23-12=11
12+11,23+11,34+11........
by adding continusly or applying the equation (12 +9×11). we get the 10th term
10th term of the arthmetic sequence is 111.
b,yes 1111 is a term of this sequence.
=(a+110d)
=(12+110×11)
=13222
