Concept: Mathematics
When you multiply a number by something to the 10 power of something then you move whatever place of the exponential to the right if its positive and left if it's negative.
- 1.365 × 10^1
- You see its positive 1 hence we move one space to the right
- Our answer is now 13.65
You keep doing the same thing
- 1.365 × 10^2
- 136.5
Lastly
- 1.365 ×10^3
- 1365

Answer:
-2 - 5n
Step-by-step explanation:
-7, -12, -17, -22, -27.....
Arithmetic Sequence
first term a = -7
difference = d = -12 - (-7) = -12 + 7 = (-5)
nth term = a + (n-1)d
= -7 + (n-1)*(-5)
= -7 + (-5)*n -1 * (-5)
= -7 - 5n + 5
= -2 - 5n
