Answer: - 799
Step-by-step explanation:
The term of a sequence
Tn = a + ( n - 1 )d where a = first term , n = the number of terms and d = the common difference.
From the Arithmetic Sequence, a = 29, n = 70 while d = 17 - 29 = -12
To calculate d, always deduct the first term from the second term and so on.
Now substitute for the values in the formula to find the 70th term
T(70) = 29 + ( 70 - 1 ) x -12
= 29 + 69 x -12
= 29 - 828
= -799.
Therefore the 70th term of the sequence
= -799
