Common difference of  $x+\frac{4x}{3}+\frac{5x}{3}+2x+x\; +\; \backslash frac\{4x\}\{3\}\; +\; \backslash frac\{5x\}\{3\}\; +\; 2x+$ ……… is

The common difference of the A.P 13, 8, 3, -2, …………… is

 If a = -1, d = -3 in an A.P, then $12^{th}12^\{th\}$ term is

If the first term of an A.P is -2 and common difference is -5, then $12^{th}12^\{th\}$ term is

If $n^{th}n^\{th\}$ term of an A.P is $\frac{5n-4}{7}\backslash frac\{5n-4\}\{7\}$ then common difference is

In an A.P if $8^{th}8^\{th\}$ term is 23 and $102^{nd}102^\{nd\}$ term is 305, then common difference is

In an A.P. if first term is 4,$9^{th}9^\{th\}$ term is 20, then $15^{th}15^\{th\}$ term is

In an A.P if third term is 7 and seventh term is 15, then first term is

In an A.P, if $16^{th}16^\{th\}$ term is 47 and $31^{st}31^\{st\}$ term is 92, then $27^{th}27^\{th\}$ term is

In an A.P, if 7 times of 7th term is equal to 11 times of 11th term, then 18th term is
