<span>let the numbers be 2n-2,2n,2n + 2 then sum of squares will be 12 n ^2 + 8 = 116 which implies n = 3.numbers are 4,6,8 </span>
given,
1st term(a)= -2
2nd term (t2) =-12
3rd term (t3) =-60
4th term(t4)= -120
here common ratio (r)=t2/t1=t4/t3
or, -12/-2= -120/-60
or,6=2
hence,no -12, -60, -120 aren't in a geometric sequence because their common ratio aren't same.

A=B times H
Given: Parallelogram length = 11 cm triangle atop the parallelogram :
short leg = 7 cm : Right triangle inside the parallelogram :
long leg = 9cmArea of parallelogram =
base * heightA = 11cm * 9cmA = 99 cm²
Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²
Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²
