Hey dear....
Here is your answer...
Here, we have to find the sum of first twelve odd natural numbers.
Therefore, 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 +17 + 19 + 21 + 23 = (12)2 = 144
Hope it helps you!!!!

Soltution:--
firs term(a) = 1
commen diffrence(d) = 2
term (n) = 12
by Sn = n/2[2a+(n-1)d]
Sn = 12/2[ 2×1+(12-1)×2]
Sn= 6×[ 2+22]
Sn= 6×24
[ Sn= 144 ]ans
