For the given series 10, 7, 4, ..... (-62). Find the 11th term from the end.
-24
-32
-338
60
Here, first term, a=10, common difference, d=7–10 = –3, last term, l=–62,
we know,
last term =a+(n–1)d –62=10+(n–1)(–3) –72=(n–1)(–3) n–1=24n=25The 11th term from the last term will be the 15th term from the start.So, a15=a+(n−1)d=10+(15–1)(–3)=10–42=–32i.e., the 11th term from the last term is –32
The correct answer is option (2) : -32
