Answer:
- The first car costs $40 and the price difference is $5
Step-by-step explanation:
<u>Given:</u>
- There are 17 cars with the price as an AP sequence.
- The total of 17 is $1360
<u>The total of last 3 is $345, it means the total of the first 14 is:</u>
<u>Use the sum of the first n terms formula, consider the first term is a and common difference is d:</u>
<u>Find it at n = 14 and n = 17:</u>
- S₁₄ = (2a + 13d)*14/2 = 1015 ⇒ 2a + 13d = 1015/7 ⇒ 2a + 13d = 145
- S₁₆ = (2a + 16d)*17/2 = 1360 ⇒ 2a + 16d = 2*1360/17 ⇒ 2a + 16d = 160
<u>Subtract the equations and solve for d:</u>
- 16d - 13d = 160 - 145
- 3d = 15
- d = 5
<u>Find the value of a:</u>
- 2a + 13*5 = 145
- 2a + 65 = 145
- 2a = 80
- a = 40
0<n>-1, -1<n(not equal to)0, n is greater than or equal to 1
