• Q15.$\sum _{\text{r}=1}^{\text{n}}\sum _{\text{q}=1}^{\text{r}}\sum _{\text{p}=1}^{\text{q}}1$ is equal to

• Q16.If ${\text{p}}^{\text{a}}={\text{q}}^{\text{b}}={\text{r}}^{\text{c}}$, where a, b, c are unequal positive numbers and p, q, r are in GP, then ${\text{a}}^{3}+{\text{c}}^{3}$ is :

• Q17.The sum to infinity of the series, $1+2\left(1-\frac{1}{\text{k}}\right)+3{\left(1-\frac{1}{\text{k}}\right)}^{2}+\dots$ is

• Q18.In the given sequence 1, 3, 6, 10, 15, …, 5050 find the number of terms

• Q19.The sum of infinite terms of the series $\frac{9}{{5}^{2}.2.1}+\frac{13}{{5}^{3}.3.2}+\frac{17}{{5}^{4}.4.3}+\dots$ is :

$\mathrm{log}m+\mathrm{log}\frac{{m}^{2}}{n}+\mathrm{log}\frac{{m}^{3}}{{n}^{2}}+\mathrm{log}\frac{{m}^{4}}{{n}^{3}}+\dots$
• Q21.If $1+\text{m}+{\text{m}}^{2}+\dots +{\text{m}}^{\text{n}}=\left(1+\text{m}\right)\left(1+{\text{m}}^{2}\right)\left(1+{\text{m}}^{4}\right)\left(1+{\text{m}}^{8}\right)\left(1+{\text{m}}^{16}\right)$, then the value n is (where$n\in N$)
