ANUP KUMAR   10 years AGO

1st digit of previous no. and sum of all digit
= next no.
so,previous no. is 137
ist digit of no.=1 and sum of all digit=1+3+7=11
so,next no. is 111

1+6= 7 it will be next num starting and second digit will be 1st num (16) ten's place number i.e 1 => 71 similarly
7+1=8 => 87
8+7=15=>158
1+5+8=14=> 141
1+4+1=6=>61
6+1=7=>76

16..1+6=7 and place first digit of previous number next to 7 to get 71 as next number.

similarly next number after 137 (1+3+7=11) will be 111.

Pargat Pal Singh   10 years AGO

Add most significant digit as least significant digit by placing it after sum of digits of previous number to get next number.
as 16..1+6=7.. put 1 after 7 to get 71.
71...1+7=8.. put 7 after 8 to get 87.
..
similarly
137..1+3+7=11.. put 1 after 11 to get 111.

The numbers 16, 71, 87, 158, 141, 61, 76, 137 are in sequence as follows:

16(6+1)=7 and first digit 1
the next is 71
and so on
the last number is 137
sum=1+3+7=11 and first digit is 1
so next number in the series is 111

megha   10 years AGO

Answer is 8: 111
Each number in the series is equal to addition of all the digits of previous number followed by the first digit of the previous number.
After 16,
2nd no. is 71, 1+6=7(all digits of previous no.) followed by 1(1st digit of previous no.)
Similarly 3rd is 87, (7+1=8 & 7)
4th 158, (8+7=15 & 8)
5th 141, (1+5+8=14 & 1)
6th 61, (1+4+1=6 & 1)
7th 76, (6+1=7 & 6)
8th 137, (7+6=13 & 7)
9th 111, (1+3+7=11 & 1)

the next number is found by summing all the digits of the previous number followed by the first digit of the previous number.

ashish kumar   10 years AGO

the digit on the left most of the number in sequence is the unit digit for the next number.
16 so 1 is at left most so in 71 ,1 is at the unit digit.
besides the unit digit of the next no in the sequence the rest digit is the sum of previous no.
16=1+6=7 at tens place and 1 at unit's place=71
71=7+1=8 at tens place and 7 at unit place=87
87=8+7=15 at left most place and 8 at units place=158
and so on..........
137=1+3+7=11 at left most place and 1 at unit place=111

the ans is 8) 111.

from the following sequence,

the addition of each digit of a number is the first digit of the next number and another digit is obtained by the first digit of the previous number.

here, 1+6=7 and 1(first digit of 16)

7+1=8 and 7(first digit of 71)

8+7=15 and 8(first digit of 87)

1+5+8=14 and 1(first digit of 158)

1+4+1=6 and 1(first digit of 141)

6+1=7 and 6(first digit of 61)

7+6=13 and 7(first digit of 76)

1+3+7=11 and 1(first digit of 137)

Given sequence is
16 71 87 158 141 61 76 137 ----
On observing the sequence
-----------------------------------------
case-I

we can get the unit digit from the leftmost digit of the previous number
from 16 we can get unit digit of 71 as 1
from 71 we can get unit digit of 87 as 7
and so on from 137 we can get the unit digit of answer as 1
---------------------------------------------
case II

The left most digits can be obtained by adding the digits of the previous number
from 16 we can get (1+6=7) as the leftmost digit of the 71 as 7
from 71 we can get (1+7=8) as the leftmost digit of the 87 as 8
and so on..........
from 137 we can get (1+3+7=11) as the leftmost digit of the answer as 11

First digit of the number is the last digit of the next number.
Adding the digits will give remaining digits before the last digit.
For e.g. 1 + 6 = 7, Hence the next number is 71
7 + 1 = 8, Hence the next number is 87
Therefore 1 +3 + 7 = 11, Hence the next number is 111
