Answer:10
Step-by-step explanation:
Adds 7 each time
31 - 3 = 28
Going from first term to fifth term is 4 increases.
28 ÷ 4 = 7
This means we have a common difference of 7.
Sequence is 3, 10, 17, 24, 31
Table:
x 0,1
y -2,0

Answer:
4000 nm
Conversion from meters to nanometers: 1 meter is 1(10⁹) nm
Step 1: Convert 0.000004 to scientific notation
0.000004 = 4(10⁻⁶)
Step 2: Convert by multiplication
4(10⁻⁶) x 1(10⁹) = 4000 nm
2.5 or 5/2
2x-3=2
2x=5 (both sides plus 3)
x=5/2 or 2.5(divid by 2 on both sides)
