Here , a=10, d=7-10=-3, L =-62,
L = a+( n-1) d
so,.
= -62=10+(n-1) (-3)
= -72 =( n-1)(-3)
n-1= 24
n=25
so,there are 25 terms in the given AP.,
a15=10+(15-1)(-3)=10-42=-32
so, the 11 the term , which is now required term is -32.
L = a+( n-1) d
so,.
= -62=10+(n-1) (-3)
= -72 =( n-1)(-3)
n-1= 24
n=25
so,there are 25 terms in the given AP.,
a15=10+(15-1)(-3)=10-42=-32
so, the 11 the term , which is now required term is -32.
