Matematika Rumus suku ke-n barisan 5,10,15,20... adalah ...​

Rumus suku ke-n barisan 5,10,15,20... adalah ...​

suku pertama (a) = 5

beda (b) = 10 - 5 = 5

rumus suku ke-n

un = a + (n - 1) b

un = 5 + (n - 1) 5

un = 5 + 5n - 5

un = 5n

Jawaban:

a = 5

b = U2 - U1 = 10 - 5= 5

Un = a + (n-1)b

= 5 + (n-1)5

= 5 + 5n - 5

= 5n
