Answer:
A) 78
Step-by-step explanation:
The given sequence is an arithmetic sequence.
Here A1 = -6, common difference = (3/2)
nth term An = a1 + (n -1)d
A57 = -6 + (57 -1)3/2
= -6 + (56)*3/2
= -6 + 28*3
= -6 + 84
A57 = 78
Thank you.
x=11
10 less than three times a number is 23
3x-10=23
3x=33
yes you would be correct if they started with zero yards at the beginning
