1,3,5,7,9,..50 find the term of sequence for this?	Choose the correct choice from the following answers.
A) 1809 B) 1879 C) 1247 D) 1900 E) 2500
This is an arithmetic progression, and we can write down   a=1a=1 ,d=2d=2 , n=50n=50 .   We now use the formula, so that   Sn=12n(2a+(n−1)l)Sn=12n(2a+(n−1)l)   S50=12×50×(2×1+(50−1)×2)S50=12×50×(2×1+(50−1)×2)   =25×(2+49×2)=25×(2+49×2)   =25×(2+98)=25×(2+98)   =2500=2500 .   2500
