Question

The sum of two consecutive terms in the arithmetic sequence 4,9,14,19,... is 503; find these two terms

Answer 1

notice that in ur sequence, there is a common difference of 5...that means u add 5 to each number to get to the next number.

so 2 consecutive terms would be : x and x + 5

x + x + 5 = 503
2x + 5 = 503
2x = 503 - 5
2x = 498
x = 498/2
x = 249

x + 5 = 249 + 5 = 254

so ur 2 numbers are : 249 and 254
