Diketahui a = 100 dan S7 = 160, hitunglah nilai b ….

A.  5

B. 8

C. 9

D. 10

Answer explanation

b = selisih antara nilai-nilai dua suku yang berurutan
a = besarnya suku pertama atau S1
Sn = a + (n – 1)b ? S7 = a + (7 – 1)b
160 = 100 + (7-1) b ? 160 = 100 + 6 b
- 6 b = 100 – 160 ? - 6 b = - 60
b = - 60 / -6 = 10

Diketahui a = 100 dan n = 16, b = 10, hitunglah D16…

2600

2000

3800

2800

Answer explanation

Sn = a + (n – 1)b

S16 = 100 + (16 – 1)10
S16 = 100 + 15.10

S16 = 100 + 150

S16 = 250
D16 = jumlah nilai-nilai sampai dengan suku ke n
Dn = n/2 (a + Sn)

D16 = 16/2 (100 + 250)
D16 = 8 . 350 = 2.800
