What is the next number of the following sequence.
1. 49, 7, 98, 16, 4, 48, 9, 3, ?
2. 36, 25, 5, ?
Read Solution (Total 12)
-
- 1.49,7,98,16,4,48,9,3
Divide it into 3 groups
(49,7,98),(16,4,48),(9,3,x)
Here 49*2=98
16*3=48
similarly 9*4=36 So x=36
(or)
7*(7)=49
7*(14)=98
And here (7*2)=14
4*(4)=16
4*(12)=48
And here (4*3=12)
Similarly,
3*(3)=9
3*(x)=36
And 3*(x i.e 4)=12
So result will be:
(9,3,x) i.e 3*12 = 36 - 10 years agoHelpfull: Yes(20) No(0)
- 2.
3+6=9
2+5=7
0+5=5
0+3=3
sum of the numbers are in difrnc of 2 - 10 years agoHelpfull: Yes(8) No(1)
- ans: 125
49*2=98
16*3=48
9*4=36
25*5=125
so ans is 125 - 10 years agoHelpfull: Yes(7) No(1)
- 1.49,7,98,16,4,48,9,3,36,25,5
Divide it into 4 groups
(49,7,98),(16,4,48),(9,3,36),(25,5,x)
Here 49*2=98
16*3=48
9*4=36
Similarly 25*5 = 125 - 10 years agoHelpfull: Yes(6) No(0)
- (49,7,98),(16,4,48),(9,3,x)
7^2=49 & 98/7= 14
4^2=16 & 48/4=12
3^2=9 & x/3=10
thus x=30 - 10 years agoHelpfull: Yes(5) No(4)
- 1. Number series will be 36
2. 6 - 10 years agoHelpfull: Yes(2) No(1)
- ans:125
49*2=98
16*3=48
9*4=36
25*5=125 dats it - 10 years agoHelpfull: Yes(1) No(0)
- 7*7=49, 7 ,49*2=98, 4*4=16, 4, 16*3=48, 3*3=9, 3,9*3=27
3+6=9,2+5=7,5 ,3 odd no.
- 10 years agoHelpfull: Yes(0) No(1)
- 1. ans;- 36
(49,7,98),(16,4,48),(9,3,x)
Here 49*2=98
16*3=48
similarly 9*4=36 So x=36
2. ans:- (6^2,5^2) is similar to (5^1,*^1) so *is 4 because base reduce by 1 i.e 6 to 5,it is similar to 5 to 4 and power is same for first case but reduce by 1 in 2nd case
- 10 years agoHelpfull: Yes(0) No(3)
- 1. 18
49 + (7)^2 = 98
16 + (4)^2 = 48
9 + (3)^2 = 18
- 10 years agoHelpfull: Yes(0) No(3)
- 1. ans: 30 7*7=49,7*1=7,7*14=98,so... 3*10=30
2. ans: 6 - 10 years agoHelpfull: Yes(0) No(2)
- 1. 7X7=49
49X2=98
4X4=16
16X3=48
3X3=9
9X4=36...and so on - 8 years agoHelpfull: Yes(0) No(0)
