Write an explicit formula for an, the nth term of the sequence 8, 16, 24, ....

Vanyuwa [196]

Answer:

For an nth term U(n) = a + (n -1)d

n = number of terms

a = first term

d = common difference

a = 8

d = 16 - 8 = 8

U(n) = 8 + (n-1)8

= 8 + 8n - 8

= 8n

The formula for the sequence is 8n

Hope this helps.
