Answer:

17

Explanation:

You need to use the formula for Arithmetic Sequences.


a_(n)=a_(1)+(n-1)d

You need to plug in the value for
a_(1) which is just the first value in your sequence. As well as
n which is the term your looking for, in this case it's 48. Lastly
d which is the amount that the pattern is increasing or decreasing by. If the sequence is increasing then the
d is positive but if the sequence is decreasing then the
d\\ is negative.
