Question

if an = 26 -4n ,then its 10th term is -

Answer 1

Answer:

58

Step-by-step explanation:

put n= 1 then you got a1 =22 and then put n = 2 you got common difference 4 then put 22+9*4=58

Answer 2

$\rm{ \: If \: \: \sf{an = 26 -4n} , \: then \: \: its \: \: 10th \: \: term \: \: is \: - \: ? }$

$\\  \bf{ \huge \:  \underline{ \underline{Answer}}\: : }$

$\sf \: an = 26 \: – \: 4 \: n$

$\\ \sf10th \: \: term = \: a10$

$\tt \: To \: \: find \: \: the \: \: 10th \: \: term , \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \tt \: we \: \: should \: \: substitute \: \: n=10 \: \: in \: \: the \: \: given \: \: equation.$

$\sf \: an = 26 \: – \: 4 \: n$

$\sf \: a10 = 26 - 4(10) \\ \\ \: \: \: \: = 26 - 40 \\ \\ \: =\underline{\underline{ ( - 14)}}$

$\\ \boxed{\bf \: a10 = ( - 14)}$
