When n = 1, 2(1) + 1 = 3
When n = 2, 2(2) + 1 = 5
When n = 3, 2(3) + 1 = 7
When n = 4, 2(4) + 1 = 9
When n = 5, 2(5) + 1 = 11
Sum = 3 + 5 + 7 + 9 + 11 = 35

Answer: 35
----------------------------------------------------
Please write that as 4.321 × 10^(−4). The " ^ " indicates exponentiation and the parentheses help make clear that your exponent here is a negative one.
Rewrite 4.321 × 10^(−4) by moving the decimal point 4 places to the left:
0.0004321
37.8*0.08=3.024
37.8-3.024=34.776
round to the nearest tenths place for currency
and the answer is $34.78
