Question

find the sum of all odd number between 5 and 200​

Answer 1

Answer:

The sum of odd numbers from 5 to 205 is 10605.

Step-by-step explanation:

It is an AP with a = 5 and d = 2.

Tn = 205 = a+(n-1)d = 5 +(n-1)*2

200/2 = 100 = n-1, or n = 101.

S101 = (101/2)[2*5+ (101–1)*2]

= (101/2)[10+200]

= 101*210/2

= 10605.
