Question

R = 1 + 4 + 9 + 16 + … + 144 ayudaaaaaaaaaaaaaaaaaaaaaa porfavor

Answer 1

Respuesta:

R = 650

Explicación paso a paso:

R = 1 + 4 + 9 + 16 + ... + 144

n = √144

n = 12

R = 12(12 + 1) × (2 × 12 + 1) / 6

R = 12 × 13(2 × 12 + 1) / 6

R = 12 × 13(24 + 1) / 6

R = 2 × 13(24 + 1)

R = 2 × 13 × 25

R = 650
