Answer:

5700

Step-by-step explanation:

By arithmetic progression ,

2+4+6+8+10+12…..+150

Sum= n/2(first term+last term)  [1st term=2; last term=150]

=75/2(2+150)

=75(76)

=5700


swarnamala2711: 2+4+6…..150

Sum=n/2(first term+last term)

=75/2(2+150)

=75(76)

=5700 is the answer dude.

Even numbers between 1 and 150 are


2,4,6.....,148


Sum=2+4+6...+148=2(1+2+3+...+74)


=2*(n(n+1))/2=n(n+1)


n=74


Sum=74*75=5550
