1 + 5 + 9 + 13 + 17 +…. + x =507528
Ta có 5 = 2 + 3; 9 = 4 + 5; 13 = 6 + 7; 17 = 8 + 9…
Suy ra x = a (a + 1) (với a ϵ N)
Nên 1 + 5 + 9 + 13 + 17 +…. + x = 1 + 2 + 3 + 4 + 5 + 6 + 7 + ….+ a (a + 1) =507528
Hay ( a + 1) (a + 1 + 1) : 2 = 1225
( a + 1) (a + 2) = 1225 x 2 = 2450 = 49 x 50
=> a = 48
=> x = 48 x ( 48 + 1 ) = 2352
