262
Step-by-step explanation:
Step 1:
To find the nth term of a sequence the basic formula is
Sn = (n*d) + (a-d)
Whereas
Sn= nth Term
n= Term to be found
d= Difference between the terms in the sequence
a= First term in the sequence
Step 2:
Sn = (130*2) +(4-2)
= 260+2
Sn= 262
The nth term for the given problem is 262
The lowest one is 4, just multiply the first fraction by 2
Answer:
x = 15
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ KLM is an external angle of the triangle, thus
∠ KLM = ∠ JKL + ∠ KJL , substitute values
5x - 7 = x + 20 + 2x + 3
5x - 7 = 3x + 23 ( subtract 3x from both sides )
2x - 7 = 23 ( add 7 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
