Required Answer:-

To find the sum of all even number from 1 to 130.

AP be 2,4,6,8 . . . . . . 260.

• The first term, a = 2.
• Common difference, d = 2.
• Total number of terms, n = 130.

Sn = n/2 × (a + Tn)

=> Sn = n/2 × (a + Tn)

=> 130/2 × (2 + 260)

=> (130 × 262)/2

=> 34060/2

Here,

2 + 4 + 6 + 8 + . . . . .+ 260 = 17030

Therefore,

17030 is the sum of even number from 1 to 130.
