find term of sequence from below series?
1,3,5,7,9,....50 Choose the correct choice from the following options.
A) 1235 B) 1458 C) 1600 D) 1809 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
