What is the next number of the following sequence.
68, 76.5, 91.8, 103.275, 123.93, .....

OPtion

1) 162.46
2) 145.265
3) 152.375
4) 159.175
5) 165.24
6) 165.245
7) 172.45
8) 184.26
9) 172.24
10)148.35

Solution

68
68/8 + 68 = 8.5+68 = 76.5 (Divide by last digit + number)
76.5/5 + 76.5 = 15.3+76.5 = 91.8
91.8/8 + 91.8 = 11.475+91.8 = 103.275
103.275/5 + 103.275 = 20.655+103.275 = 123.93
Similarly
123.93/3 + 123.93 = 41.31+123.93 = 165.24

Option 5)

Correct Option: 5 Best Solution (7)

ABHINAV PUSHPAM   8 years AGO

Logic- No./last digit + no.
68/8 = 8.5 + 68 = 76.5
76.5/5 = 15.3 + 76.5 = 91.8
91.8 /8 = 11.475 + 91.8 = 103.275
Similarly,
123.93/3 = 41.31 + 123.93 = 165.24

Option 5)

no/last digit+ no
68/8 +68=76.5
76.5/5+76.5=91.8

similarly
123.93/3+123.93=165.24
option 5

Divide each last digit by the number then after adding the quotient you'll get the final answer.

SAKSHI SUMAN   8 years AGO

divide the number with its last digit and add the quotient to the number

68/8=8.5+68=76.5
76.5/5=15.3+76.5=91.8
and so on
so 123.93/3=41.31+123.93=165.24

Jaikumar Bhatia   8 years AGO

(68)+(68)/8=68+8.5=76.5
(76.5)+(76.5)/5=76.5+15.3=91.8
(91.8)=(91.8)+(91.8)/8=91.8+11.475=103.275
(103.275)+(103.275)/5=103.275+20.655=123.93
(123.93)+(123.93)/3=123.93+41.31=165.24
Ans is =165.24
Option is (5)

Bijina cp    8 years AGO

68+(68/8)=76.5
76.5+(76.5/5)=91.8
91.8+(91.8/8)=103.275
103.275+(103.275/5)=123.93
123.93+(123.93/3)=165.24

1) Divide the last digit of the previous number by 2
2) Divide the previous number with the number obtained in step (1) above.
3) Now divide the number obtained in step (2) by 2
4) Add this number to the previous number to get the next number.
In 68, 8/2 = 4
68/4 = 17
17/2 = 8.5
68 + 8.5 = 76.5

76.5 = 5/2 = 2.5 = 76.5/2.5 = 30.6 = 30.6/2 = 15.3 = 76.5 + 15.3 = 91.8

91.8 = 8/2 = 4 = 91.8/4 = 22.95 = 22.95/2 = 11.475 = 91.8 + 11.475 = 103.275

103.275 = 5/2 = 2.5 = 103.275/2.5 = 41.31 = 41.31/2 = 20.655 = 103.275 + 20.655 = 123.93

123.93 = 3/2 = 1.5 = 123.93/1.5 = 82.62 = 82.62/2 = 41.31 = 123.93 + 41.31 = 165.24
