Answer:
-68 is not a term in the given sequence
Step-by-step explanation:
The given sequence is -12, -17, -22, -27...
There is a common difference of d=-17--12=-5
The explicit rule for this sequence is
Or
To find the term that has a value of -68 we equate the explicit formula and solve for n.
The position should be a natural number.
Since n is a decimal, it tells us that -68 is not a term in the given sequence
