Answer:

15350

Step-by-step explanation:

Given,

Series : 5 + 8 + 11 + ...... + 302

The given series is in AP.

The common difference,

8 - 5 = 3

11 - 8 = 3

So, common difference, d = 3

first term, a = 5

last term, l = 302

an = a + (n - 1) d

302 = 5 + (n - 1)3

297 ÷ 3 = n - 1

99 + 1 = n

n = 100

Sum of n terms of an AP, Sn = n/2[a + l]

= 100/2 [ 5 + 302]

50 × 307
