Question

K+5
P. =11(k-1)k÷2+3
K+1. P
K
Find K

Answer 1

K= -5
P= 11(-5 -1 ) -5 ÷ 7
=11(-6)-5÷7
=11×30 ÷7
=330 ÷7
=47.14
when k+1×p then
-5 +1 × 47.14
-4 × 47.14
= -188.56

Answer 2

$\large\bf{\underline\purple{❥solution:-}}$

❥K= -5

❥P= 11(-5 -1 ) -5 ÷ 7

=11(-6)-5÷7

=11×30 ÷7

=330 ÷7

=47.14

❥when k+1×p then

-5 +1 × 47.14
