Hey....
Here you go....
Answer:
A.P. = 12, 16, 20, 24, 28, .....248
a = 12, d = 14, an = 248
an = a + (n-1) d
248 = 12 + (n-1)4
n - 1 = 236/4
n = 59 + 1 = 60.
So there are 60 multiples of 4 lie between 10 and 250.
Sn = (n/2) + (a + an) = (60/2) + (12+248) = 7800

I didn't asked to find the sum. I asked "how many"!
It's not between 10 and 250 , it's between 10 and 205
so what? !
