At 60mph, how far will a car travel in 2 1/2 hours?

Step-by-step explanation:

150 miles cause 6x2 is 12 and half of 6 is 3 so 12+3 is 15 just add a zero at the end

150 miles

Step-by-step explanation:

if its 60mph, multiply 60 × 2 1/2

120 + 30 = 150miles

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
