The sum of the successor and the predecessor of 5,00,000 is

Step 1

Successor of 5,00,000 =

5,00,000 + 1 = 5,00,001

Predecessor of 5,00,000 =

5,00,000 -1 = 4,99,999

Step 2

Sum of the successor & Predecessor = 5,00,001 + 4,99,999

= 10,00,000

$\stackrel{1}{5},\stackrel{1}{0}\stackrel{1}{0},\stackrel{1}{0},\stackrel{1}{0},1+\underset{–}{4,99,999}\underset{–}{10,00,000}$

Answer = 10,00,000
