complete the pattern and give reason,
23, 28, 38, 49, 62, ?.
In the given pattern sum of the digits of the number is added to the number.
i.e.
23 + 2 + 3 = 28
28 + 2 + 8 = 38
38 + 3 + 8 = 49
49 + 4 + 9 = 62
62 + 6 + 2 = 70
Hence the required number is 70
and the completed pattern is 23, 28, 38, 49, 62, 70.
