Q. If n+7 represents an even number, the next larger even number is represented by(1) n+8(3) 10n+7(2) n+9(4) 2n+7
Identify nature of n+7: Identify the nature of n+7. Since n+7 is even, n must be odd (even + odd = odd, odd + odd = even).
Determine next even number: Determine the expression for the next larger even number. Adding 2 to an even number results in the next even number. Thus, (n+7)+2=n+9.
Check correct expression: Check the options for the correct expression.The correct expression representing the next larger even number is n+9.
