A certain amount of bacteria doubles every 10 mins. If the number of bacteria initially was 10 what will be the number of population after 1 hr?



I think the answer will be 640.
am i right

0 0 0
Initially it is 10
 means a=10
its grow double after 1o min interval
means if it is x then after 10 min it should be  2x then 2(2x) then 2(2(2x))) and so on ........... this show that it is in geometric progression
tn=ar^n-1 is formula to calculate number in n position
10 min interval between 60 min.
n=6+1( including initial 0 minute)
a=10 as we know through question
put all values in above formula
t7=10 X2^7-1
answer is 640
