Question

ii) B = {3, 10, 29, 66, 127}
write in roster form..​

Answer 1

Answer:

Take the series 3,10,29,66,127

now note the difference between successive terms

10-3=7

29-10=19

66-29=37

127-66=61

Now as you have got the difference

Let us arrange it in a firm if series

7,19,37,61

Now take the difference between these terms

19-7=12

37-19=18

61-37=24

So the difference is a multiple of 6

So the next difference is 30.

X-61=30

X=91

So now looking to our original series

after 127 the next no is 127+91=218

X-127=91

So next number in the series is 218
