What’s the nth term for 3,4.5,6,7.5

Step-by-step explanation:

The following sequence is in AP

Suppose the first term is denoted by"a" and the common difference by"d"

a=3

d=4.5-3= 1.5

the nth term = a + (n-1)d

= 3+(n-1)1.5

=3+1.5n -1.5

=1.5+1.5n

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:
