Hi!
The pattern is to add 17.
The equation the find the 25th term of an arithmetic sequence is
a(n) = a(1) + (n - 1)d
n = the 25th term
a = the first number in the sequence
d = the pattern
a(25) = -33 + (25 - 1)17
Solve
a(25) = -33 + 24 * 17
a(25) = -33 + 408
a(25) = 375
The 25th term in the sequence is 375
Hope this helps! :)
