Answer:
u = 7
Step-by-step explanation:
In a parallelogram, GI = GK so:
u + 28 = 5u
4u = 28
u = 7

Answer:
Step-by-step explanation:
The sum of geometric sequence:
S n = a 1 * ( q^n - 1 ) / ( q - 1 )
where: a 1 = 1,
q = a 2 : a 1 = 4 : 1 = 4
S 8 = 1 * ( 4^(8) - 1 ) / ( 4 - 1 ) =
= ( 65,536 - 1 ) / ( 4 - 1 ) = 65,535 / 3 = 21,845
