hi
u0 = 64 with u(n+1) = un *0.75
u3 = 64 *0.75^3 = 27
sum is : 64 * ( 0.75^4 -1) / 0.75-1 = 175
manual proof : 64 + 48+36+27 = 175

It's just the black part and the empty square under which is 1/2 and the red square with the empty square under is 1/2 so it's 1/2 x 1/2
1% of 120 is 1.2, so 7 *1.2 = 8.4
Also you could set up the proportion 7/100 = x/120 and solve for x.
Answer:
The inequality for this would be n ≥ 20.
We know this because it must be larger than 40. We also know it can possibly be equal because the statement says "at least".
