Explanation:
It can be observed that the number of trees planted by the students is in an AP.
1,2,3,4,5………………..12
First term, a=1
Common difference, d=2−1=1
S
n
=
2
n
[2a+(n−1)d]
S
12
=
2
12
[2(1)+(12−1)(1)]
=6(2+11)
=6(13)
=78
Therefore, number of trees planted by 1 section of the classes =78
Number of trees planted by 3 sections of the classes = 3×78=234
Therefore, 234 trees will be planted by the students.
