The factor of 20 that is not a multiple of 2 is 5. We found this by identifying the factors of 20 and checking which ones are not multiples of 2. The only number that fits this criterion is 5.

U4 = 8Sn = n/2 x (a + Un)S4 = 4/2 x (2 + 8)S4 = 2 x 10S4 = 20U10 = a + (n-1) x bU10 = 2 + (10-1) x 2U10 = 2 + 9 x 2U10 = 20S10 = n/2 x (a + U10)S10 = 10/2 x (2 + 20)S10 = 5 x 22S10 = 110Jadi jumlah 4 suku pertama adalah 20jumlah 10 suku pertama adalah 110
