Step-by-step explanation:

hey dude here's your answer...

since you want sum of whole number

a=1 t2=2

tn=100

n=?

d=2-1=1

d=1

tn =a+(n-1)d

100=1+(n-1)1

100=1+n-1

n=100

if u want sum of first 100 whole nos

then u have to use Sn formula

Sn =n/2[2a+(n-1)d]

Sn=100/2[2×1+(100-1)1]

Sn=50×2+99

Sn=199

therefore sum of first 100 whole number is 199

please mark me as brainliest I need it very much
