What is the missing number.
802, 786, 744, ....., 674, 650

OPtion

1) 710
2) 714
3) 726
4) 718
5) 722
6) 716
7) 736
8) 728
9) 732
10)None of these

Solution

802
802 - (8*2) = 802-16 = 786 (Number - (last*first)number)
786 - (7*6) = 786-42 = 744
=> 744 - (7*4) = 744-28 = 716 <=
716 - (7*6) = 716-42 = 674
674 - (6*4) = 674-24 = 650

Option 6)

Correct Option: 6 Best Solution (21)

ABHINAV PUSHPAM   8 years AGO

Logic-> no. - 1st digit*last digit = new digit.

802
802- 8*2 = 786
786- 7*6 = 744
Similarly
744- 7*4 = 716

Option 6)

RAVAL   8 years AGO

802 = 8 * 2 = 16 so 802 - 16 = 786
783 = 7 * 6 = 42 so 786 - 42 = 744
same here,
744 = 7 * 4 = 28 so 744 - 28 = 716.
answer is 716

744-28=716
716-42=674......
answer is 716

Sandip Das   8 years AGO

the difference of 802 and 786 is 16
(100th digit *unit digit) = 8*2=16
802-16=786
follow the same way
786 - (7*6)=744
744 - (7*4)=716
716 - (7*6)=674
674 - (6*4)=650
so the ans is 716

Praveenkumar P Kalikeri   8 years AGO

802 -(8)(2) = 786
786 -(7)(6) = 744
744 -(7)(4) = 716
716 -(7)(6) = 674

Gaurab Kumar Jha   8 years AGO

the difference between them is the product of first and ladt digit so,
744 the product of first and last digit is 28 so we substract 28 from 744 and we get 716 and the next term will be 744 - (7*4) i,e 674 which is give hence our result is right and that is 716

multiply unit and hundreds digit and subtract it from the number to get next number

802
802-(8×2)=786
786-(7×6)=744
744-(7×4)=716
716-(7×6)=674
674-(6×4)=650

Anusha Reddy   8 years AGO

802---8*2=16
so 802-16=786
786----7*6=42
so 786-42=744
Similarly do for all numbers
744---7*4=28
744-28=716

ANUJ KUMAR   8 years AGO

the second term in the sequence is: difference of first number and the product of one's & hundred's digit of first number.
Ex. 786 = 802-8*2
744 = 786-7*6
Now the required term
716 = 744-7*4

802 = 802 - (8*2) = 802 - 16 = 786 [first digit * last digit]
786 = 786 - (7*6) = 786 - 42 = 744
744 = 744 - (7*4) = 744 - 28 = 716 -------answer
716 = 716 - (7*6) = 716 - 42 = 674

Subtract product of digits at hundred place and unit place to get next number.
802 - 8*2= 786
786 - 7*6= 744
744 - 7*4= 716
716 - 7*6= 674
