First term is -7, so a_1 = -7
To get the next term, we add on 4. We can see this if we subtract like so
d = (2nd term) - (1st term) = (-3) - (-7) = -3+7 = 4
So d = 4 is the common difference.
Apply a_1 = -7 and d = 4 to get...
a_n = a_1 + d*(n-1)
a_n = -7 + 4*(n-1)
a_n = -7 + (n-1)*4

<span>4 9/10 divided by 2 3/5
</span>4 9/10 = 49/10
2 3/5 = 13/5
so
(49/10) / (13/5)
=49/10 * 5/13
= 49/26
or
= 1 23/26
