47
15
16
20
The sum (m + n)th term and (m - n)th terms of an A.P is equal to twice the
nthterm
mthterm
(m - 1)term
n + 1 term
nth term of the following sequence ak, ak3, ak5.......is
akn
ak2n-1
ak2n
akn+1
Common ratio of the series 1/4 + 1/2 + 1.........is 256?
10th term
11th term
12th term
9th term
Common ratio of G.P am-n, am, am+n.........is
am
a-m
an
a-n
nth term of the sequence 2, -4, 8, -16 is
an = 3an-1 + 1
an = n(n-3)/n+4
an = n2 + 1
an = (-1)n-12n
If the sum of 3 numbers in A.P is 24 and their product is 440, then the numbers are
5, 8, 11
6, 9, 12
7, 10, 13
4, 8, 12
The 10th common term between the series 3+7+11+................ and 1+6+11+----- is
191
193
211
None of these.
The sequence an = 2n + 1 is an A.P Then the common difference is
5
7
3
2
There are 15 terms in an A.P. Its first term is 5 and common difference is 3, then its middle term is
