if a_n is even , a_n = a_(n-1) plus 188
if a_n is odd, a_n = a_(n-1) plus 192


∴ a_6 = a_5 plus 188

This is also possible- first two digits are increasing as gradual multiplication of 19 & last digit is alternatively 5 or 3

also, the difference between successive terms alternates between 188 and 192
