69, 93, 108, 125, .......

OPtion

1) 142
2) 139
3) 133
4) 146
5) 135
6) 138
7) 143
8) 148
9) 132
10)None of these

Solution

69
[69+(6+9)]+9 = (69+15)+9 = 84+9 = 93
[93+(9+3)]+3 = (93+12)+3 = 105+3 = 108
[108+(1+0+8)]+8 = (108+9)+8 = 117+8 = 125
Similarly
[125+(1+2+5)]+5 = (125+8)+5 = 133+5 = 138

Mukund Manohar   8 years AGO

Previous No. + Sum of digits + (Last Digit * 2) = Next Number.
69 = 69 + 6 + (9*2) = 69 + 24 = 93
93=93 + 9 + (3*2)=93 + 15 = 108
108=108 + 1 + 0 + (8*2) = 108 + 17 = 125
125=125 + 1 + 2 + (5*2) = 125 + 13 = 138

Aakash Beniwal   8 years AGO

sum of all digit + last digit i.e.
(6+9) + 9 = 15
add 15 to 69
similarly
(1+2+5) + 5 =13
add 13 to 125
answer is 138 .
