Question

tolong ya jawab ini...​

Answer 1

Penjelasan dengan langkah-langkah:

1.

U14 = a + 13b

U14 = 2 + 13(4)

U14 = 2 + 52

U14 = 54

2.

U55 = a + 54b

U55 = 7 + 54(8)

U55 = 7 + 432

U55 = 439

3.

U25 = a + 24b

U25 = 1 + 24(2)

U25 = 1 + 48

U25 = 49

4.

U40 = a + 39b

U40 = 7 + 39(-2)

U40 = 7 - 78

U40 = -71

5.

U15 = 15(16)/2

U15 = 15(8)

U15 = 120
