Answer:
The students got 3 signatures on first day.
Step-by-step explanation:
We are given the following in the question:
The number of signatures students get each day is 3 times as many as the day before.
Thus, the number of signatures form a geometric progression with common ratio 3.
Number of signatures on sixth day =
term in a geometric progression is given by:
where a is the first term of the series and r is the common ratio.
Thus, the first term of geometric progression is 3.
Thus, the students got 3 signatures on first day.
