Question

Find the
Sum of the following
APS :0.6,1.7,2.8 .....to 100 terms

​

Answer 1

Answer: 1105

Step-by-step explanation:

First write the given things i.e.

a= 0.6

d= 1.1

n=100

Answer 2

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

$\large\tt\purple{a=0.6}$

$\large\tt\purple{d=1.7-0.6=1.1}$

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

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

$\longrightarrow$$\large\tt\purple{S100=\frac{100}{2}(2(0.6)+(100-1)1.1)}$

$\longrightarrow$$\large\tt\purple{S100=50(1.2+99×1.1)}$

$\longrightarrow$$\large\tt\purple{S100=50(110.1)}$

$\longrightarrow$$\large\tt\purple{S100=5505}$
