Answer:
Fourth term of given arithmetic progression a(4) = 30
Step-by-step explanation:
Given incomplete information:
a(n) = 7n – 1 9
Assume Correct information:
a(n) = 7(n – 1) + 9
Find:
Fourth term of given arithmetic progression
Computation:
Fourth term of given arithmetic progression = a(4)
So,
Number of term (n) = 4
So,
a(n) = 7(n – 1) + 9
a(4) = 7(4 – 1) + 9
a(4) = 7(3) + 9
a(4) = 21 + 9
a(4) = 30
Fourth term of given arithmetic progression a(4) = 30
