We know the Sum of the First n terms of an Arithmetic Progression which is
n/2[a + (n-1)d]
The given series can be divided into two
There for
4+8+12...16 where a = 4, d= 4
Based on above equation summation of first series will be 16/2[4 + (16-1)4] = 512
similarly
3+5+7+...to 16 where a = 3, d = 2
then summation will be 16/2[3 + (16-1)2] = 264
4+3+8+5+12+7+...to 32 Terms = 4+8+12...to 16 Terms + 3+5+7+...to 16 Terms
so 512 + 264 = 776
our Answer is 776
