Question

Tolong yang jago matematika nomer 3 bagian a,b,c.dengan caranya

Answer 1

a) a = 2 , b = U2-U1 = 4-2 = 2

b) a = 3, b = U2-U1 = 6-9 = 3

c) a = 5, b = 3

Answer 2

a. U9=2+(9-1)2=2+(8)2=2+16=18

U11=2+(11-1)2=2+(10)2=2+20=22

b. U10=3+(10-1)3=3+(9)3=3+27=30

U15=3+(15-1)3=3+(14)3=3+42=45

c. U21=5+(21-1)3=5+(20)3=5+60=65

U28=5+(28-1)3=5+(27)3=5+81=86
