Question. ) The sum of three in AP in 293 and their sum of square is 27 . Find the numbers
★ Answer. ) We know that three numbers is AP have to be taken as : a-d , a , a+d
According to Question .
→ a - d + a + a + d = 27
→ 3a = 27
Value of ' a ' = 9
Three numbers are = 9 - d , 9 , 9+d .
→ (9 - d )^2 + 81 + ( 9+ d )^2 = 293
Solving the above , value of ' d ' will come :
→ d = ± 5
Numbers are = 4 , 9 , 14
