Tolonkkk pelisssg nrima asal asalan.​

Penjelasan dengan langkah-langkah:

a. U5

= 4 – 3(5)

= 4 – 15

= -11

b. U1 + U2

= 4 – 3(1) + 4 – 3(2)

= 4 – 3 + 4 – 6

= 1 + -2

= -1

c. U4 – U3

= 4 – 3(4) – 4 – 3(3)

= 4 – 12 – 4 – 9

= -8 – 4 – 9

= -8 + (-4) – 9

= -12 – 9

= -12 + (-9)

= -21

Un = 4-3n

Jawab:

a) U5 = 4 – 3(5) = 4-15 = -11

b) U1 + U2 = [4-3(1)] + [4-3(2)] = 1 + (-2) = -1

c) U4 – U3 = [4-3(4)] + [4-3(3)] = -8 + (-5) = -13
