The third term in an arithmetic sequence is 10 and the fifth term is 26. if the first term is a(1) which is an equation for the nth term of this sequence?
1) a(n) = 8n + 10
2) a(n) = 8n - 14
3) a(n) = 16n + 10
4) a(n) = 16n - 38

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
