Question

calcular la suma de los primeros 17 terminos de an=2+1/2(n-1)

Answer 1

a1 = 2 + 1/2 (1 - 1) = 5/2

a2 = 2 + 1/2 (2 - 1) = 5/2

a3 = 2 + 1/2 (3 - 1) = 3

a4 = 2 + 1/2 (4 - 1) = 7/2

a5 = 2 + 1/2 (5 - 1) = 4

a6 = 2 + 1/2 (6 - 1) = 9/2

a7 = 2 + 1/2 (7 - 1) = 5

a8 = 2 + 1/2 (8 - 1) = 11/2

a9 = 2 + 1/2 (9 - 1) = 6

a10 = 2 + 1/2 (10 - 1) = 13/2

a11 = 2 + 1/2 (11 - 1) = 7

a12 = 2 + 1/2 (12 - 1) = 15/2

a13 = 2 + 1/2 (13 - 1) = 8

a14 = 2 + 1/2 (14 - 1) = 17/2

a15 = 2 + 1/2 (15 - 1) = 9

a16 = 2 + 1/2 (16 - 1) = 19/2

a17 = 2 + 1/2 (17 - 1) = 10
