Question

Find the sum of all odd integers between 300 and 498

Answer 1

hi my

here's your answer

Step-by-step explanation:

number of odd integers between 300 and 497=(497-301)/2=98

Therefore, number of odd integers between 300 and 498 = 98+1 = 99

Sum of Arithmetic progressions  = ,n/2(a+l) where 'a' is the first term and 'l' is the last term.

Sum of odd integers between 300 to 498

= 99/2(301+497)=39501.
