Just apply the summation formula of arithmetic progression
2+4+6…..150
Sum=n/2(first term+last term)
=75/2(2+150)
=75(76)
=5700
2+4+6…..150
Sum=n/2(first term+last term)
=75/2(2+150)
=75(76)
=5700

✌✌hey here is ur ans ...✌✌
here
a = 2
an = 150
d = 2
an = a + ( n - 1 ) d
= 150 = 2 + ( n -1) × 2
= 150 - 2 = 2n - 2
= 148 + 2 = 2n
= n = 150 /2
= n = 75
Now
Sn = n/2 ( an + a )
Sn = 75/2 ( 150 + 2 )
Sn = 75/2 × 152
Sn = 75 × 76
Sn = 5700
hope it will help uh ..
nd plz mark as brainliest ..☺☺
