tuliskan lima suku pertama barisan aritmatika jika diketahiu a=5 dan b=2/5 Please tolong bantu kak besok di kumpul

a = 5
b= 2/5

a = u1

maka,
u1 = 5

u2 = u1 + b
u2 = 5 + 2/5 = 27/5

u3= u2 + b
u3 = 27/5 + 2/5 = 29/5

u4 = u3 + b
u4 = 29/5 + 2/5 = 31/5

u5 = u4 + h
u5 = 31/5 + 2/5 = 33/5

#maaf klo salah
