​

Answer 1

${\small{\bold{\purple{\underline{ Given }}}}}$

$\longrightarrow \: \sf if \: a = 20 \: d = 3 \: then \: find \: t10$

$\red{ \boxed{\sf{Answer}}}$

• Using Formula Of A.P

• Given :- a=20, d=3

• Find :- tn

$\sf{ \green{➙Sᴏʟᴜᴛɪᴏɴ}}$

• ⟶ Now ,

• tn = a + (n -1 ) x d

• tn = 20 + ( n - 1) x 3

• tn = 20 n x 3

• tn = 60 / n

• tn = 60

$\longrightarrow \sf \: Final \: Answer \: = > tn = 60$
