Answer 2

Answer:

465

Step-by-step explanation:

GIVEN:

• Odd numbers
• 1,3,5,7............30

NEED TO FIND:-

• Its sum

SOLUTION:-

We know that,

${\boxed{S_{n} = \frac{n}{2} (a + l)}}$

where,

• $S_{n}$- sum of n numbers in series.
• $n$ - total number of numbers in series.
• $a$ - first number of series.
• $l$ - last number of series.

Here,

$a=1$

$l=30$

$n=30$

$= \frac{30}{2} (1 + 30)$

$= 15 \times 31$

$= 465$

HOPE THAT HELPS!!
