When n = 1 first term = -6
n = 2 second term = 0
n = 3 third term = 6
n = 4 4th term = 12
so we have an Arithmetic sequence first term = -6 and common difference = 6
Sum 14 terms = (14/2)[2*-6 + (14-1)*6]
= 462 answer
Well the way I multiply bigger numbers is like this...
43 x 42
43
42
3 times 2 equals six
then 4 times 2 is 8
then add your zero place
then 4 times 3
and then 4 times 4
Or..something like this.
Answer:
50 hours
Step-by-step explanation:
Josh = 50 hours
frank worked 50 hours less and twice as many hours as josh did.
