What the nth term of 9,11,13,15,17

= 2n + 7

Step-by-step explanation:

Note the differences between consecutive terms are constant, that is11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2 ← common difference

Thus the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 9 and d = 2, thus

= 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7

step-by-step explanation:

its 512 because parenthesis and to the 2nd power is 512 so it will be 512
