Question

write an ap having 5 as the first term and -2 as the common difference ?

Answer 1

solution :-

in question given term


first term (a) = 5

and common difference ( d) = - 2


in question we have find ap term.


then we putting the values of a and d in general formula.

a

a + d

a + 2d

a + 3d


............ get



first

5

second = 5 + (-2)

= 3

third term

a + 2d

5 +(2 ×-2)

= 1


fourth term

a + 3d

5 + 3(-2)

5+(-6)

= -1


so term are following


5. ,3 , 1. ,-1 .....

it's showing the required ap.


be brainly

Answer 2

$here \: is \: the \: solution \\ let \: a = 5 \: and \: d = - 2 \\ in \: general \: we \: have \\ Tn =a+(n-1)d \\ so \: \: T1=5 \\ T2=5+(2-1)(-2) = 3 \\ similarly \: \: \: T3=1 \: \\ T4=-1 \\ T5=-3 \\ T6=-5 \\ so \: the \: requierd \: ap \: is \: \: 5,3,1,-1,-3,-5............$
