The first four terms are -6, -7, -9 and -13.
Step-by-step explanation:
- Step 1: Given first term, a(1) = -6 and the nth term, a(n) = 2a(n-1) + 5. FInd the first four terms.
⇒ a(1) = -6
⇒ a(2) = 2a(1) + 5 = 2 × -6 + 5 = -12 + 5 = -7
⇒ a(3) = 2a(2) + 5 = 2 × -7 + 5 = -14 + 5 = -9
⇒ a(4) = 2a(3) + 5 = 2 × -9 + 5 = -18 + 5 = -13
you need to change 1 3/8 into a mixed fraction, which would be 11/8, but with this fraction, you need to do the reciprocal, which would be 8/11 multiplied by 3/4. You can cross simplify 8 and 4 changing the fractions being multiplied to 2/11 and 3/1. Then you need to multiply straight across, which would get an answer of 6/11.
