1. Find the sum of the following AP: 2.7.12to 10 terms
06.17.28to 100 terms
please answer

245 and 55050

Step-by-step explanation:

The sum to n terms of an AP is

= [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

In the first progression a₁ = 2 and d = 7 - 2 = 5, thus

= [ (2 × 2) + (9 × 5) ] = 5 × ( 4 + 45 ) = 5 × 49 = 245

-------------------------------------------------------------------------------

In the second progression a₁ = 6 and d = 17 - 6 = 11, thus

= [ (2 × 6) + (99 × 11) ]

      = 50(12 + 1089) = 50 × 1101 = 55050
