How many terms are in the sequence 5, 8, 11..........47?
47
15
16
20
In a G.P if the (p + q)th term is m and (p - q)th term is n then its pth term is
0
m * n
√mn
1/2 (m + n)
The sequence an = 3n - 2 is an A.P, then a and d are
1, 4
4, 7
1, 3
7, 10
What is the 20th term of the sequence defined by an = (n - 1)(2 - n) (3 + n)?
7866
-7866
7688
-7688
If the third term of a G.P is 10, then the product of first 5 terms is
101
50
510
105
The 10th term of an A.P is 52 and 16th terms is 82. Then the 32nd term is
162
165
173
None of these
In an A.P, if the sum of first n terms is Sn = n2 P and sum of first m terms is Sm = m2P, where m, n, p are positive integers and m ≠ n then Sp is
n2Sp
m2p/n2
(m2 + n2)P
P3
If the sum of n terms of an A.P is (Pn + qn2) where p and q are constants. Then the common difference is
2 + q
2q
2/q
2 - q
If G is geometric mean of numbers a and b then G =
√ab
±√ab
ab
