Question

Find the sum of all even number from 1 to350

Answer 1

hey here is your answer.....
__________________________☺️

even numbers between 1 to 350 or from starting to 350 are ... 2,4,6,8,10,12........350
which forms an A.P and we have a formula for this that sum of n even numbers = n(n+1)
so nth term = 350/2 =175. n = 175
n(n+1) = 175(175+1) = 175 ×176 = 30800

hope it helps..........
