Answer:

-12.5%

Step-by-step explanation:

A percentage change is computed using ...

percent change = ((new amount) -(original amount))/(original amount) × 100%

We want to find the percentage change from 4.8 m, so we have ...

percent change = (4.2 -4.8)/4.8 × 100% = -.6/4.8×100% = -12.5%

The carpenter made the track 12.5% too short.

i=3 → N=(3–1)*5+2=2*5+2=10+2=12
i=4 → N=(4–1)*5+2=3*5+2=15+2=17
i=5 → N=(5–1)*5+2=4*5+2=20+2=22
i=6 → N=(6–1)*5+2=5*5+2=25+2=27
