Jawaban:
-166
Penjelasan dengan langkah-langkah:
U1 = a = 32
b = U2 - U1 = 21 - 32 = -11
Un = a + (n-1)b
Un = 32 + (n-1)-11
Un = 32 -11n + 11
Un = 43 - 11n
U19 = 43 - 11.19
U19 = 43 - 209
U19 = -166
32,21,10,-1
dapat dilihat setiap suku selalu -11
artinya
a = 32
b = -11
Un = a+(n-1) b
U19 = 32+(19-1) -11
U19 = 32 + (18) -11
U19 = 32 + -198
