Question

Find the 50th term of the AP 10 , 15, 20, 25
pls i need it pls help me pls ​

Answer 1

given: a = 10, d = 15 - 10 => 5, n = 50

50th term => A50 = a + 49d

=> A50 = 10 + 49×5

=> A50 = 10 + 245

=> A50 = 255

therefore 50th term = 255

Answer 2

Answer:

The 50th term of the AP 10 , 15, 20, 25 is 255.

Step-by-step explanation:

Given: AP is 10 , 15, 20, 25

First term (a) = 10

Difference (d) = 15 - 10 = 5

n = 50

an = a+(n − 1)d

$a_{50} = 10 + (50 -1) 5$

= 10 + 49 (5)

= 10 + 245

= 255

So, the 50th term of the AP 10 , 15, 20, 25 is 255.
