If initially there are ‘n’ bacteria, their number grows to ‘3n + 8’ after one second because of the birth of new bacteria. The number of bacteria grows in this manner for 10 seconds. It is known that no bacterium dies in the first 10 seconds. If the number of new bacteria born in the 5th second is 8748, how many bacteria were born in the 1st second?

He increae 50% then he can keep 8 old and 8 more in that 50% so in half he keep 16 so in full (old) he keep 32 and now he have 8 extra so 32+8=40 here in this new place he can keep 8 more but present he has 40 only
