hitunglah jumlah suku ke 10 dari deret aritmatika 16+19+22+...!

bantu jwb dg caranya!!​

Jawab:

16,19,22,...

Rumus pola aritmatika: Un = a + (n- 1)b

a = U1

= 16

b = U2 - U1

= 19 - 16

= 3

U10 = a + (10 - 1)b

U10 = 16 + 9 x 3

U10 = 16 + 27

U10 = 43

Rumus jumlah suku ke-n pertama:

Sn = n/2 (a + Un)

S10 = 10/2 (16 + U10)

S10 = 5 (16 + 43)

S10 = 5 x 59

S10 = 295

Jawaban akhir: 295

Jawaban:

43

Penjelasan dengan langkah-langkah:

a = 16

b = 19 - 16 = 3

Un = a + ( n - 1 ) b

= 16 + ( 10 - 1 ) 3

= 16 + 9.3

= 16 + 27

= 43

semoga membantuuuu
