Jawab:

pola I

n = 1 --> 1

n = 2 --> (1 + 1(4))

n = 3 --> (1 + 2(4))

n = 4 --> (1 + 3(4))

n = 5 --> (1 + 4(4))

...

un = 1 + (n-1)4

un = 1 + 4(n- 1)

u61 = 1 +4 (61-1)

u61 = 1 + 4(60)

u61 = 1 + 240

u61 = 241

Pola 2

u1 = 1

u2 = 5

u3 = 9

u4 = 13

a = 1

b = 9-5 = 4

Un = a +(n-1)b

u61 = 1 + 60(4)

u61 = 1 + 240

u61 = 241
