What is the explicit formula of a1=-3,d=2

The explicit formula for the given expression is 2 n - 3

Step-by-step explanation:

Here, the first term of sequence  =  -1

The common difference  = 2

In a ARITHMETIC PROGRESSION:

The nth term of a sequence is given as

a(n) =  a + (n-1) d

⇒ Here, a(n)  = -1 + (n-1)(2)

                      = -1 + 2n -2

                       = 2n - 3

or,  a(n)  =  2n - 3

Hence, the explicit formula for the given expression is 2n - 3.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
