PLEASE HELP!!<br><br> what is the explicit formula for this sequence -7, -4, -1, 2, 5
trasher [3.6K]

Answer:

The explicit formula for the given expression is a_n=-10+3n.

Step-by-step explanation:

The given sequence is

-7, -4, -1, 2, 5

The difference between two consecutive terms is same, therefore the given sequence is an arithmetic sequence.

The first term of the given AP is -7 and the common difference is

-4-(-7)=-4+7=3

The explicit formula for an AP is

a_n=a+(n-1)d

Where, a is first term, d is common difference and n is number of terms.

Substitute a=-7 and d=3 in the above equation.

a_n=-7+(n-1)3

a_n=-7+3n-3

a_n=-10+3n

Therefore the explicit formula for the given expression is a_n=-10+3n.

(-4)(-4) use an exponent to rewrite the expression
DiKsa [7]
For this case we have the following expression:
<span> (-4)(-4) &#10;
 By properties of exponents we have:
 Same basis, the exponents are added.
 We have then:
 (-4)^{1+1}
 Then, rewriting the exponent we have:
 (-4)^{2}
 Therefore, an exponent to rewrite the expression is:
 2
 Answer:
 
(-4)^{2}
 an exponent to rewrite the expression is 2.</span>
