B . 5635.6% not for sure but I think that’s the answer
An=a1+d(n-1)
a1=first term
an=nth term
d=common dffernce
given
first term is -5
it increases by 1
an=-5+1(n-1)
a10
a10=-5+1(10-1)
a10=-5+1(9)
a10=-5+9
a10=4
10th term or a10 is 4
74 + 35 + 16 + 45 =
= 74 + 16 + 35 + 45
= 70 + 4 + 10 + 6 + 30 + 5 + 40 + 5
= 70 + 10 + 4 + 6 + 30 + 40 + 5 + 5
= 80 + 10 + 70 + 10
= 80 + 10 + 10 + 70
= 100 + 70
= 170
