Question

Sum of first positive 200 numbers

Answer 1

Answer:

Therefore, the sum of the first 200 positive integers (i.e., 1 to 200) is 5,050 + 15,050 = 20,100.

Answer 2

Answer: 20100

Step-by-step explanation:

First positive 200 terms forms an A.P.

A.P. : 1,2,3,4,5,..........................,200

here,

a = 1

an = 200

So,

Sum of first n terms, Sn = n(a+an)/2

S200 = 200(1+200)/2

S200 = 100(1+200)

S200 = 100 × 201

S200 = 20100

Hence,the sum of first positive 200 terms = 20100
