sum of 11numbers = 11 x 50 = 550
sum of first 6 no.s = 6 x 49 = 294
sum of last 6 no.s = 6 x 52 = 312
sum of last 5 no.s = sum of 11 no.s - sum of first 6 no.s
so, = 550 - 294 = 256
so six term = sum of last 6 no.s - sum of last 5 no.s
= 312 - 256 = 56
sum of first 6 no.s = 6 x 49 = 294
sum of last 6 no.s = 6 x 52 = 312
sum of last 5 no.s = sum of 11 no.s - sum of first 6 no.s
so, = 550 - 294 = 256
so six term = sum of last 6 no.s - sum of last 5 no.s
= 312 - 256 = 56
