Question

-37,-33,-29,.....to 12 terms

Answer 1

-25,-21,-17,-14,-10,-6,-2

Answer 2

$\large\sf\red{GIVEN:-}$

$\large\tt\purple{a=37}$

$\large\tt\purple{d=-33-(-37)=4}$

$\small\tt\green{The\:sum\:of\:n\:terms\:of\:an\:AP\:is\:given\:by}$

$\longrightarrow$$\large\tt\purple{Sn=\frac{n}{2}(2a+(n-1)d)}$

$\longrightarrow$$\large\tt\purple{S12=\frac{12}{2}(2(37)+(12-1)4)}$

$\longrightarrow$$\large\tt\purple{S12=6(-74+44)}$

$\longrightarrow$$\large\tt\purple{S12=-180}$
