Answer 2

Answer:

Step-by-step explanation:

natural no. b/w 100 & 300 forms an AP which mean,

required AP = 101,102,103,.....299

Sn= a+(n-1)d    where,a=101& d=1

Tn=a+(n-1)d

299=101+(n-1)1

299=101+n-1

n=299-100

n=199

therefore,

S199=199/2[2*101+198*1]

199/2[202+198]

199/2[400]

199*200

39800 is the sum of all natural no.s b/w 100 & 300
