We have,
14−0=14;12−14=14;
This shows that the difference of a term and the preceding term is always the same. Hence, the given sequence form an AP.
nth term tn=a+(n−1)d
a= First term
d= Common difference
n= number of terms
tn=nth term
Here first term a=0 and common difference d=14
Therefore,
a5=a+4d=0+4×14
⇒a5=0+1=1
a6=a+5d=0+5×14
⇒a5=54
a7=a+6d=0+6×14
⇒a7=32
Hence, the next three terms are 1,54,32
