Answer:
Hey!
The 6th term of your sequence is 23!
Step-by-step explanation:
<u>This is how you get it...</u>
1) T6=3n+5 (the 6th term and the equation...)
2. We now do T6=3(6)+5 (3 x 6 then add 5)
3. In other words... T6=18+5
4. We work it out 18 + 5 = 23
HOPE THIS HELPS!!

The answer is 5^7 because you add the exponents
A = 7n + 2
a₁ = 7*1 + 2 = 9
a₂ = 7*2 + 2 = 16
a₃ = 7*3 + 2 = 23
.
.
.
a₂₀ = 7*20 + 2 = 142
This is an Arithmetic progression, a = 9, last term = 142
Sum of the 20 terms using: n/2(a + l) where l = last term.
= 20/2(9 + 142)
= 10 * 151
= 1510
Sum of the first 20 terms = 1510
