Question

For the arithmetic sequence –17, -7,3, 13,..., find a 35оа-321.Ob323ос-323Od289

Answer 1

We have the next sequence

-17,-7,3,13

first we need to find the difference between each value

-17+d=-7

d=17-7

d=10

then we have the next formula in order to find any number in the sequence

`a_n=a_1+d(n-1)`

in our case

n=35

a1=-17

therefore for a35

`a_(35)=-17+10(35-1)`
`a_(35)=323`

therefore the answer is 323
