Which is the 19th term in the sequence: an = -2(n - 3)?
a n = - 2 ( n - 3 )
n = 19
a 19 = - 2 ( 19 - 3 )
a 19 = - 2 * 16
a 19 = - 32
what are the first three terms of the sequence a1=2 and an=3(an-1)2
To find the 19th term in the sequence, we need to substitute the value of n as 19 into the given formula for the sequence.
Given: an = -2(n - 3)
To find the 19th term, substitute n = 19:
a19 = -2(19 - 3)
Now, simplify the expression within parentheses:
a19 = -2(16)
Multiply -2 by 16:
a19 = -32
Therefore, the 19th term in the sequence is -32.
