Twice the sum of consecutive numbers n and n + 1 is 510.Type the correct answer in each box. Use numerals instead of words.The smaller number isIThe larger number isSubmit

Answer 1

we know that

The algebraic expression is equal to

2(n+n+1)=510

solve for n

2(2n+1)=510

4n+2=510

4n=510-2

4n=508

n=127

therefore

the numbers are

127

and

128

so

The smaller number is 127

The larger number is 128
