Answer:

Step-by-step explanation:

let correct term be x and wrong term is y

∴a1+a2+a3+--------a99+y =100*50

⇒a1+a2+a3------------a99= 5000-y                       -----------1

∴a1+a2+a3+a4--------a99+x=100*150

⇒a1+a2+a3------------a99=15000-x                        --------------2

∴eq1 =eq2

⇒5000-y=15000-x

⇒x-y=10000
