Step-by-step explanation:

The smallest natural numbr divisible by 4=4

the largest number inside 100 =96

thus a=4

d=8-4=4

n=?

an=96

an=a+(n-1)d

96=4+(n-1)4

96-4=4n-4

92+4=4n

96=4n

n=96/4

n=24

you can directly find n by directly multiplying 96/4

now,

sn=n/2(2a+(n-1)d)

or

sn=n/2(a+l)

 

so when we do it,we get

sn=24/2(4+96)

sn=1200

hope it helps!!
