a=5
d=2
n=101
Sn=n/2 [2a+(n-1)d]
= 101/2 *[2(5)+(101-1)2]
= 101/2 [10+200]
=101/2*210
=101*105
=10605
:.Sum of the series is 10605
d=2
n=101
Sn=n/2 [2a+(n-1)d]
= 101/2 *[2(5)+(101-1)2]
= 101/2 [10+200]
=101/2*210
=101*105
=10605
:.Sum of the series is 10605

Use,
Sn=n/2[2a+(n-1)d]
Here
n=101
a=5(First term of series)
d=7-5=2
now solve it,
Sn=n/2[2a+(n-1)d]
Here
n=101
a=5(First term of series)
d=7-5=2
now solve it,
