What is the next number of the following sequence
48,49,57,59,36,39,28,32
Read Solution (Total 8)
-
- Next numbers will be: 24, 19.
Explanation:
(48, 49, 57, 59)(36, 39, 28, 32),(x,y)
Fist number decreasing by 12 so x = 24
if u observe the difference of consecutive terms:
49-48=1
59-57=2
39-36=3
32-28=4
29-24=5 and so on..
so y = 29 - 10 years agoHelpfull: Yes(4) No(3)

- group the elements in to two
Odd Group: 48 57 36 28
Even Group: 49 59 39 32
see the first digit of the odd group numbers
it is, 4,5,3,2 so the first digit for the next number should be 1
now see the second digits of the odd group numbers
_8, _7, _6, again _8 so the next number should have the second digit as 7
so the next number should be 17

- the next series is 18,23
(48,49)-diff is 1
(57,59)-diff is 2
(36,39)-diif is 3
(28,32)-diff is 4 - 10 years agoHelpfull: Yes(1) No(1)
- 48+49+57=154
59+36+39=134
so
28+32+x=114 -->x=54

- 48 49
57 59
36 39
28 32
17 ans - 10 years agoHelpfull: Yes(0) No(9)
- 49-48=1
59-57=2
39-36=3
32-32=4
57-49=8
59-36=23
39-28=11=8+3
next num will be 32+23+3=58 - 10 years agoHelpfull: Yes(0) No(2)
