Jawaban dengan langkah-langkah:
U3 = 11, U7= 19
U7 - U3 = a + 6b - a + 2b
19 - 11 = 4b
8 = 4b
8/4 = b
2 = b
Un = a + (n - 1) b
U3 = a + (3 - 1) 2
11 = a + (2) 2
11 = a + 4
11 - 4 = a
7 = a
U11 = 7 + (11 - 1) 2
U11 = 7 + (10) 2
U11 = 7 + 20
U11 = 27
Jawaban:
Penjelasan:
U3 = a+2b = 11
U7 = a+6b = 19
-------------- -
-4b = -8
b = -8/-4
b = 2
U3 = a+2b
11 = a+2(2)
11 = a+4
a = 11-4
a = 7
U11 = a+(n-1)b
U11 = 7+(11-1)2
U11 = 7+(10)2
U11 = 7+20
