How do you solve this?

Find the sum of the first 8 terms of the following sequence. round to the nearest hundredth if necessary.

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2
