I got 110 because 35+35=70 and 180-70=110. I added 35 to 35 because it says that AB=AD, so they should make congruent angles. So add the 35+35 and work from there.
The appropriate formula here is l = a + (n-1)d, where l represents the last term.
Here the first term is -5 and the common difference is +4. Thus,
l = -5 + (n-1)(4) (answer)
Check: we are given the arith sequence -5, -1, 3, 7. Does our formula correctly predict the 1st term? l = -5 + (1-1)(4) = > -5. Yes.
Does it correctly predict the 3rd term? l = -5 +(3-1)(4) => -5+2(4) = 3. Yes
Answer:
The 12th term in the sequence is b(12)= -26
Step-by-step explanation:
For the 12th term, that means we need to find what the value of b is when n=12
To find b:
- Substitute all 'n' with 12 (since its the 12th term)
b(n)= -4-2(n-1)
b(12)= -4-2(12-1)
- Solve the equation in order of BEDMAS (aka PEDMAS)
b(12)= -4-2(11)
= -4- (2*11)
= -4-(22)
= -26
The 12th term in the sequence is b(12)= -26
