You can put this solution on YOUR website!
a%28n%29=a%281%29%2B%28n-1%29d
a%2899%29=a%281%29%2B98%2Ad=351
a%28100%29=a%281%29%2B99%2Ad=353
a%28100%29-a%2899%29=a%281%29%2B99d-a%281%29-98d
a%28100%29-a%2899%29=d
d=353-351
d=2
Then,
a%281%29%2B98d=351
a%281%29%2B98%282%29=351
a%281%29=351-196
a%281%29=155
.

.
a%282%29=a%281%29%2Bd=155%2B2=157
a%283%29=a%281%29%2B2d=155%2B4=159
I think you see how to get the next 2 values so I'll leave that to you.
