• B. 8, 18
• C. 5, 10
• D. 18, 16
• E. None of these

Answer 1

The correct option is B 8, 18

Next number is (1$\times$unit\ digit)+(sum of all digits)So first tem is 4.
2nd Term = (1$\times$4)+(0+4)= 8
3rd Term = (1$\times$8)+(0+8)= 16
4th Term = (1$\times$6)+(1+6) = 13
5th Term = (1$\times$3)+(1+3)= 7
6th Term = (1$\times$7)+(0+7)= 14
7th Term = (1$\times$4)+(1+4)= 9
8th Term = (1$\times$9)+(0+9) = 18
