Answer:
The sum of first n terms of arithmetic series formula can be written as,
Sn= n/2[2a+(n−1)d]
Where n = number of terms ⇒ 100
a = first even number ⇒ 12
d = common difference of A.P. ⇒ 12
Apply the given data in the formula,
S 100 = 100/2[2×12+(100−1)12]
=50[24+(99)12]
=50[24+1188]
=50[1212]
=60,600
So, the sum of first 100 multiples of 12 is 60600.
