Answer:
no
Step-by-step explanation:
because the r value is different
r=a2/a1
=19/7
r= a3/a2
=43/19
as a1/a2 is not equal to a3/a2

yes it is following series,
first of all they are odd prime numbers.
if we seethe first digit 7, and after it 19 digits in 19 if we add them it is giving us 10 and after that 43 if we add these it give us a 7 after that 91 if we add 9 and 1 it is giving us 10 means it is following 7_10, 7_10 progression and also a odd prime number..
(hope you have understand it was my trick andopinion the answers of different people can be different)....
