bantuan anda sangat berarti :)

3.
a . 2 , 6 , 10 , 14 , 18 , 22 , 26 , 30 , 34 , 38 , 42 , dst ..
b . 1 , 4 , 7 , 10 , 13 , 16 , 19 , 22 , 25 , 28 , 31 , 34 , dst ..

cmn no.3 saja yg saya tau , trims

3 )a. 2, 6, 10, 14, 18, 22, 26, 30, 34, dst.
b. 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, dst.

4 ) 2, 5, 8, 11, ...

Un = a + (n-1)b
a = suku pertama = 2
b = beda = 3

Rumus : Un = 2 + (n-1)3
U100 = 2 + (100-1)3
U100 = 2 + 297
U100 = 594

5 ) Rumus pola bilangan segitiga pascal =
Un = 2n - 1

U6 = 2.6 - 1
U6 = 12 - 1
U6 = 11
