here,
a1=-1
a2=-1+4 =3
a3= 3+4=7
a4=7+4=11
using the general formula for nth term of an ap

Answer= a25 = 95
Surface area of sphere=100pi cm^2
4pi×r^2=100 pi
pi cancel on both sides
4×r^2=100
r^2=100/4
r^2=25
so r=5
So option b 5 cm is correct.
2/3 divided by 4= 2/3x1/4 (flip 4 around). 2x1=2 & 3x4=12. 2/12 or 1/6
