What is the next number of the following sequence
17, 24, 32, 38, 62, 74, .......

OPtion

1) 86
2) 96
3) 102
4) 108
5) 116
6) 124
7) 136
8) 148
9) 150
10)None of these

Solution

17
17+ (1*7) = 17+7 = 24
24+(2*4) = 24+8 = 32
32+(3*2) = 32+6 = 38
38+(3*8) = 38+24 = 62
62+(6*2) = 62+12 = 74
Similarly
74+(7*4) = 74+28 = 102

Sourangsu Bandyopadhyay   10 years AGO

The solution can be derived as:
First Number =17
Second Number = 17+(1*7)=24
Third Number = 24+(2*4)=32
................
................
Sixth Number = 62+(6*2)=74
Hence,
The next number in this sequence = 74+(7*4)=102
Answer = 102.

in every sequence the next no is the addition of last no and the last no\'s digits multiplication.
17+1*7=24;
24+2*4=32;
32+3*2=38;
38+3*8=62;
62+6*2=74;

subramani   10 years AGO

17
24=> (1*7)+17
Multiply previous number's each digits and add with previous number.
so (2*4)+24=32
(3*2)+32=38
(3*8)+38=62
(6*2)+62=74
from the above solution,
(7*4)+74=102
so the next number to 72 is 102.
option 3 is correct
