13 * last of 13 is 3 => 13*3=39
like that 39*9=351
now
351 so 35*1=35

17×(last digit)=17×5=85
85×(last digit)=85×5=425
42×(last digit)=42×5=210
***Please note when the result is a three digit no. we multiply the first two digits with the last digit and when it is a two digit number we will multiply both the digits with the last digit

Pragya Sahay   8 years AGO

The fourth term is given by multiplying the first two digits of the third number to the last digit i.e, 35*1=35. similarly, the last term is given by multiplying the first two digits of 6th term wit the last digit i.e. 42*5 =210. So preceding in this way the 5th term must be obtained by 17*5 = 85, hence 175 is the answer

1st number 13..last digit 3,,so 13*3=39.which is 2nd number.and last digit 9.so 39*9=351 which is 3rd number...similarly 4th number 35 and last digit 5,so 35*5=175,so the mising number is 175 .....6th number 85 ,last digit 5..so 7th number is 85*7=425...
so my answer is (9) 175 that is missing number
