= 1455
generate a few terms of the sequence using = 3n + 2
= ( 3 × 1) + 2 = 5
= (3 × 2) + 2 = 8
= (3 × 3 ) + 2 = 11
= (3 × 4 ) + 2 = 14
= ( 3 × 5 ) + 2 = 17
the terms are 5, 8, 11, 14, 17
these are the terms of an arithmetic sequence
sum to n terms is calculated using =
[ 2a + (n-1)d]
where a is the first term and d the common difference
d = 8 - 5 = 11 - 8 = 14 - 11 = 3 and = 5
=
[( 2 × 5) + (29 × 3) ]
= 15( 10 + 87) = 15 × 97 = 1455
Answer:
☪ First , Let's know about Exponential Equation :
⤿ Let's take an equation : .
In this equation , the variable ' x ' is the exponent of the base 2. Such an equation in which variable appears as an exponent of a base is known as exponential equation. The following axioms are useful while solving the exponential equations :
- If
, then
- If
, then
and x = 0
---------------------------------------------------------------
☯ Now , Let's Solve :
In this equation , the variable 'x' is the exponent of the base 8 .Write in exponential form with the base of 2
↦
Write the number 2 in exponential form with the base of 2.
↦
Since the bases are same , cut 2 on both sides and set the exponents equal.
↦
↦
Divide both sides by 3
↦
↦
And we're done!
Hope I helped!
Have a wonderful day! ツ
