Penjelasan dengan langkah-langkah:
a. Pola bilangan persegi panjang :
Un = n ( n + 1 )
U50 = 50 ( 50 + 1 )
= 50 × 51
= 2.550
b. Pola bilangan segitiga :
Un = 1/2 ( n ( n + 1 )
U50 = 1/2 ( 50 ( 50 + 1 )
= 1/2 × 50 × 51
= 76
c. Pola bilangan persegi :
Un = n²
U50 = 50²
= 2.500
d. Pola bilangan genap :
Un = 2n
U50 = 2 . 50
= 100
e. Pola bilangan ganjil :
Un = 2n - 1
U50 = 2 . 50 - 1
= 100 - 1
= 99
